QUICK START - BASIC OPERATION
The RailKing PCC Street Car contains state-of-the art electronics with
several built-in automatic features for incredibly realistic operation. Despite
these advanced features, the PCC Street Car is easy to operate with any
compatible standard AC transformer (see the compatibility chart on page
28).
All models are controlled by a ProtoSound® DCRU® electronic reverse
unit. The reverse unit operates in the same manner that all reverse units
function by using forward, neutral and reverse states that are entered each
time the throttle is turned on and off or by using the transformer direction
switch (if so equipped).
The reverse unit is designed
to ignore dirty track, dead
spots on switches or minor
short circuits without
disrupting the engine
operation, even at slow,
prototypical speeds. Once the
engine is placed on the track,
the throttle on the transformer
can be advanced. You will
see that only the car’s lights
come on and that only two dings of the ProtoSound bell occur (on
ProtoSound equipped 3-rail
models). The car does not run.
This is known as the RESET state
and is explained in more detail
beginning on Page 4. The
ProtoSound® DCRU® will not
power the motor until the throttle
is turned OFF and then ON again. At this point, the car will now function
just like any other engine equipped with an electronic or mechanical E-unit.
On ProtoSound-equipped cars, the motor sounds will change slightly in
volume as the car begins to move. The horn can be activated by pressing
the whistle button on the transformer just as any horn would be activated.
See the sections later in this guide, beginning on page 5, for more
information on activating the horn and bell sounds.

Each feature is described among the following pages. Though the system
is easy to use, we encourage you to read the instructions thoroughly.
PROTOSOUND® DCRU® REVERSE UNIT
As mentioned in the Basic Operating section, the car is controlled by a
ProtoSound® DCRU® reverse unit that contains the standard
forward-neutral-reverse states found on most reverse units. However, as
described earlier, when power is first applied to the track, the reverse unit
begins in RESET or what seems like a neutral state. Power must be
interrupted again to get the car to enter the forward state. It is this first
RESET state that gives ProtoSound® its unique, remote controlled
functions. The system will enter RESET whenever power to the track is off
for three or more seconds. NEUTRAL will be referred to as the state
between Forward and Reverse.
ProtoSounds® is equipped with a microprocessor, that, depending on the
amount of memory it is allotted, allows the user to utilize several remotely
activated functions. In the simplest terms, ProtoSounds® has its own
“Computer" controlling these functions. In fact, the power of this
microprocessor is the same as that of a 286 desktop computer! In order to
access many of these remotely controlled functions, the user must be in the
RESET state to do so. RESET is entered anytime power to the locomotive
has been off for more than 3 to 5 seconds. When the car first enters
RESET, the microprocessor initiates a system check to determine if the
system, transformer and car are operating correctly. This takes
approximately 2.2 seconds. In order for ProtoSounds® to properly initiate
the system check, do not advance the transformer throttle past 10 volts

5
RailKing PCC Street Car Operating Manual
when you first enter RESET, then slowly turn the transformer throttle to the
off position and then back on again to enter the forward phase. Interrupting
the power too quickly may cause the system to re-enter RESET (signaled by
two dings of the bell). Should this happen, wait longer before interrupting
the power to enter the Forward phase.
ProtoSounds® comes with several programmable functions, including
Engine Volume Adjustment, Separate Bell Button Operation
(pre-programmed at the factory), and Horn-In-Neutral Operation. Each of
these features are described in more detail later. You will notice that when
in RESET, your car will not respond to the whistle button with a horn blast
or continuous bell ringing. In fact, when in RESET and the whistle button
is depressed, only one single bell chime will be heard each time the whistle
button is pressed. If you don’t want to configure or change your car using
any of these programmable features, simply leave RESET after waiting 2.2
seconds by interrupting the power to put the car in forward. After you leave
RESET, your car will operate normally in all the direction states of forward,
neutral and reverse.
HORN OPERATION
Your RailKing ProtoSound® equipped street car features a digital
recording of a PCC horn. The horn sound can be activated anytime the car
is in forward or reverse by pressing the whistle button on your transformer.
The horn will continue to blow as long as the whistle button is depressed.
The horn will not function in RESET and must be configured through a
RESET option to allow the horn to work when the car is in neutral. See
page 16 for information on horn programming in theUsing RESET To
ProgramProtoSounds® section of this manual.
BELL OPERATION
Your RailKing ProtoSound® equipped PCC Street Car features a digital
recording of an actual PCC bell. Unlike previous versions of
ProtoSounds®, the bell can be turned on or off with any separate bell
button, like the Lionel® Railsounds® No. 5906 Bell Button, by simply
pushing the button. If you don’t have a separate bell button, the bell can be
controlled through your transformer’s whistle button whenever the car is in
NEUTRAL. The bell will never ring continuously in RESET (Remember
NEUTRAL is the state between Forward and Reverse). Once the bell is
turned on, it will continue to ring when the car is cycled into forward or

6
RailKing PCC Street Car Operating Manual
reverse until you press and release the bell button or re-enter NEUTRAL
and turn the bell off with the whistle button.
In fact, because of ProtoSounds® state-of-the-art design, the
microprocessor remembers its last command. Therefore, unless you turn
the bell off before you quit running your car, the next time you run the car,
the bell will come on. No matter whether you come back an hour later or a
year later, the bell will begin chiming once the car enters one of the three
directional states.
Unlike most ProtoSound® equipped engines, the PCC version of the
ProtoSound® software activates the bell in a slightly different manner.
Normally, the bell is activated by pressing the bell button. With the PCC’s
unique Trolley Announcement Sounds feature, the bell button is used to
activate the Trolley Announcements as well as to control the bell. In
addition, since most trolleys only used the bell to signal a start or stop
sequence and rarely ran with the bell constantly running, use of the bell was
normally quite limited. Nevertheless, the ProtoSound® equipped PCC bell
can be controlled by a bell button. Instead of pushing the button on to start
the bell sound, the operator must push and release the bell button quickly.
Failure to release the button quickly will activate the Trolley
Announcement feature which is described on the following pages.
To turn the bell on using the transformer’s whistle button, turn on power to
the track and cycle the engine into NEUTRAL. Turn the throttle to 8 volts
or less and press the whistle button. The bell should begin chiming. To
turn the bell off, press the whistle button again. If you want to keep the bell
on while running the car, simply interrupt the power with the transformer
throttle or the transformer directional switch and enter forward or reverse.
SQUEAKING BRAKE SOUNDS
ProtoSound® equipped engines feature the ability to play the sound of
squeaking brakes whenever your car slows in speed. The PCC is shipped
with a default setting that causes the brake sounds to play while the car is in
forward or reverse and the transformer throttle is lowered from a high
setting to a low setting (14 volts to 8 volts or less). The brakes can be
turned off through a RESET setting explained later in this manual The
sound itself is a stored record on the ProtoSounds software chip and will
always play the same brake sound for the same three second length each
time the voltage is reduced from high to low. Some practice may be

7
RailKing PCC Street Car Operating Manual
required to synchronize the playing of the brake sounds with the movement
of the car. It is not uncommon for the car to stop before the brake sound is
completed. Operators will find that by coordinating the movement of the
throttle setting from 8 volts to off
will allow the car to maintain its
movement while the brake sounds
play. Note: The brake sounds will
not be heard if the transformer
throttle is not set above 14 volts
and/or not reduced below 8 volts.
TIPS ON USING THE SQUEAKING BRAKE FEATURE
Because the squeaking brake feature always plays for approximately 3 seconds, it is
possible that the brake sounds will play longer or shorter than what visually seems
prototypical. You will find that by practicing with the brake feature, you can
determine how quickly to throttle down and what speeds and voltage settings
give you the most prototypical braking effect.
Typical users will find the feature to be a very realistic way to simulate the
sound of a car slowing down for curves, crossings or coming to a stop at a
station, side track or switch yard. As mentioned above, you will find that
initially your car may continue to play the brake sounds once it comes to a
stop or that the sounds stop prematurely before the car comes to a complete
halt. For example, if you simply run the car and turn the throttle off quickly,
the brake sounds will likely continue playing even though the car has come to
a complete stop. This annoying effect can be eliminated by simply practicing
with the brake feature. In no time, you will quickly learn how to “feather" the
throttle to keep the car moving while the brake sounds play and then turning
the throttle off just as the sounds stop.
The ProtoSound® squeaking brake feature also has the ability to simulate the
squeal of wheel flanges when your car enters a curve at high speeds. The
same brake squeaking sound plays, but you don’t need to reduce the
transformer throttle to activate the squeaking sounds. To play the squeaking
sounds as wheel flange sounds, you can trigger the brake feature with the
whistle button on the transformer. As your engine enters a curve (or anywhere
on the layout) quickly “flick" your transformer whistle button about half way.
This “flicking" action causes the transformer to release a short DC signal that
ProtoSounds® reads as an indicator to activate the brake sounds. The car
won’t slow down even though the sounds play. This simulates the wheel
flange squeal of a train traveling through a turn too quickly.
Note: Consistent activation of the wheel flange squeaking is determined by the
condition of your transformer’s whistle button rectifier disc. Older rectifier
discs may not release a clear and strong enough DC signal required by
ProtoSounds® computer to play the wheel flange squealing.

RailKing PCC Street Car Operating Manual
SELF-RECHARGING BATTERY BACKUP SYSTEM
ProtoSounds® state-of-the-art design includes a self-recharging battery
backup system for improved performance at any speed. The self-recharging
battery backup system is automatically turned on or off whenever track
power is turned on or off. There are no switches to turn on or off to enjoy
the benefits of the automatic battery backup system. The battery ensures
that power to the sound system will remain on during directional changes,
setting RESET options, or when traveling over dirty track and switches.
The battery is a rechargeable NiCad type which is continually charged
from the track when power is applied. NiCad batteries are a dry battery and
should not leak or cause any damage to your locomotive and will last up to
five years or longer. If you notice that the sounds seem distorted or garbled
at low voltages or become silent when power from the transformer is shut
off, the battery charge may be low. Before replacing the battery, you
should put the engine in NEUTRAL and leave the transformer throttle at
about 12 volts for fifteen minutes. This should temporarily recharge the
battery. If the garbled or distorted sounds are reduced, then your battery
charge has worn down. You can give your battery a full charge by leaving
the engine ON in NEUTRAL for 16 to 18 hours.
REPLACING THE PROTOSOUND BATTERY
The ProtoSound® battery is a special NiCad 7-cell, 8.4v battery - NOT the
6-cell, 7.2v battery found in most convenience stores. The 6-cell NiCad is
NOT recommended for use with ProtoSound® applications. Replacement
ProtoSound® batteries are available from MTH ProtoSound Electronics at
9693-A Gerwig Lane, Columbia, MD 21046. A standard 9v alkaline
battery can be substituted as a temporary fix, but since alkaline batteries
can’t take a charge, it will eventually wear down. Regardless, it should give
you a week to a couple of months use while you wait for your replacement
ProtoSound® battery to arrive.

RailKing PCC Street Car Operating Manual
TROLLEY ANNOUNCEMENTS (TAS)
ProtoSounds® is now equipped with operator controlled trolley
announcement sounds, hereby known as TAS. This easy to use feature
plays digitally reproduced trolley announcements and street action sounds
whenever you activate and stop your PCC car. No additional wires or
modifications are needed on your layout to enjoy these amazing sound
effects, though an option does exist that allows you to completely automate
your trolley run activating the sounds at user specified locations. The
sounds themselves are randomly generated and randomly “shuffled” on the
ProtoSounds software chip. This gives the system the ability to produce
different sounds in a different order each time the TAS feature is enabled.
These different sounds are heard each time you cycle the transformer
throttle from on to off in the same manner that you would cycle the throttle
to enter the various states of forward, neutral and reverse. The entire TAS
sequence is designed to simulate the arrival, disembarking, embarking, and
departure of a PCC stop. The sounds include the PCC driver announcing the
stop and the upcoming stop, passenger disembarking and embarking
sounds, driver to passenger requests, door openings and closing and general
street action sounds. Each is described in more detail in the following
sections.
ACTIVATING TROLLEY SOUNDS
Your ProtoSounds® equipped engine features an operator controlled
trolley announcement sound set that can be activated in one of three ways,
in automatic mode, manual mode or in layout controlled mode. Once
activated, this easy to use feature plays digitally reproduced sounds of a
trolley stop.
Option 1 - Automatic Mode: If you are using a separate bell button
controller to ring your bell (like the Lionel Railsounds No. 5906 bell
activation button) you can activate the feature by entering forward or
reverse and pressing and holding the bell button for one second at which
time the operator will
hear the driver
announce the next
trolley stop location.
Continued holding of
the bell button will be

RailKing PCC Street Car Operating Manual
followed by a special “passenger dong” sound which indicates that a
passenger wishes to exit the car at the current stop. At this point the
operator should release the bell button if he wishes to stop the car. If the
operator continues to hold the bell button down, the car will continue
traveling down the track until the operator chooses to release the bell
button. This option gives the operator the true sense of acting as the PCC
driver and responding to the passenger’s desire to leave the trolley (as heard
from the “passenger dong” sound). It also allows the operator to announce
the next stop well before coming to the desired trolley stop and precisely
control where the PCC car does finally stop. This option is the default
setting for the TAS feature.
Once the bell button is released, the PCC car will sound a single bell
“ding” and come to an automatic stop even though power to the track has
not been interrupted by the operator. Once stopped, the TAS feature will
play the sound of the doors
opening followed by the sounds
of passengers leaving the car and
others arriving. During this event,
the operator can expect to hear a
variety of different sounds,
including the driver asking the
passengers to move to the back, to
have their fare ready as well as the sounds of footsteps, general passenger
conversational sounds as well as outside street corner sounds. After a set
period of time, the operator can expect to hear the a double bell ding,
followed by the car door closing. Immediately following the door closing,
the motor will be engaged and the PCC car will automatically take off. The
TAS feature will automatically start the car back up in the same direction it
was traveling when the TAS feature was activated. So if the car was
traveling forward before TAS was activated, it will continue traveling
forward once TAS has completed.
Option 2 Manual Mode The TAS feature is armed in the same manner
as Option 1, but instead, after the “passenger dong” sound has played and
the bell button released, the car will not automatically stop. To activate the
rest of the TAS features, the operator must stop the car and place it in the
neutral position by interrupting the transformer throttle. The car will not
automatically start up again after the initial TAS sounds have played,
Instead, the sounds will continue to repeat themselves giving the operator
Release The Railsounds®
Bell Button To Stop The Car
After Hearing The
Passenger Dong Sound

11
RailKing PCC Street Car Operating Manual
the ability to leave the car at the stop for longer periods of time. When the
operator is ready to leave the stop, the transformer throttle must be
interrupted again. This will
be followed by the sound
of a double bell ding the
doors closing. After the
door closing, TAS will
automatically reengage the
motor and the car will
proceed away from the
trolley stop. Like Option 1,
the car will continue on in
the same direction it was
traveling before TAS was activated.
Option 3 - Automatic Layout Configuration The TAS feature in the
PCC car can be automatically triggered on a layout by configuring insulated
pieces of track near the designated trolley stops around the layout. The
insulated track sections (center rail only) need to be attached to the
transformer with a diode in the line to create a negative DC signal (the same
signal created by the bell button) and be long enough that the signal will be
outputted for at least 3 seconds (the time it takes to activate TAS by
pressing the bell button). In short, the insulated track section and diode are
acting like a bell button. Whenever the car runs through the insulated
section, it will receive the negative DC signal and TAS will be activated.
Because the diode reduces
the power to the track, the
car will also slow as it
enters the insulated track
section. The key to
making this option
effective is using a section
long enough to create the
3second“push” of
negative DC without
slowing the car to a
complete halt. It is
recommended that the
operator attempt to have the rear roller of the car leave the insulated track
section shortly after the 3 second push of negative DC has been received by
the ProtoSound® module inside the PCC car. This way, when TAS has

completed its sequence, the car will be sitting on a track section with
enough power to sufficiently get the car moving again. Adjusting the
overall track voltage will help adjust the speed necessary to carry the car
through the insulated track section but caution should be taken that not too
much power is on the track or the car may pass through the insulated
section before 3 seconds of negative DC was received by the ProtoSound®
module. This will be obviously the case if the car’s bell turns on instead of
it stopping.
TIPS ON USING THE TAS FEATURES
TAS is a unique feature of ProtoSounds® that can be completely controlled
by the operator or automatically configured on the layout. You decide how,
when or if you want to utilize the feature. By reviewing the following tips you
should find solutions or suggestions to the various operating scenarios you
might encounter when using TAS.
Tip#1: You can escape the TAS sequence by turning the transformer throttle
to OFF after TAS has been activated and waiting 3 seconds before turning the
throttle back ON. This will return the car to the RESET position.
Tip#2: You do not have to be in the forward state to utilize TAS. For
example if you activate the TAS feature while in reverse and interrupt the
throttle to enter neutral, you will be entering neutral before forward rather than
neutral before reverse as normally defined by the ProtoSound® sequencing.
TAS, however, remembers what direction state the car was in before activation
and will return the car to that same state upon completion of the TAS
sequence, skipping the next direction state normally found in the ProtoSound®
sequence. This will allow your car to leave the stop in the same reverse
direction that it arrived in.
Tip#3: In Auto Mode, putting the car into Neutral immediately after the car
stops (when TAS has been activated) will cause TAS to play 3 dings of the
bell, play the door closing sound and repower the car into the forward mode.
Tip#4: In Auto Mode, putting the car into Neutral after the car stops (when
TAS has been activated) and the sound of the car doors opening has played
will cause TAS to play two dings of the bell, play the door closing sound and
then proceed into the forward mode.
Tip#5: In the Track Configured Mode, interrupting the power while the car is
traveling through the insulated track section will cause TAS to sound 3 dings
of the bell, close the doors and proceed off in the reverse direction.

RailKing PCC Street Car Operating Manual
PROTOSOUND® VOLUME ADJUSTMENT
Your ProtoSound® system has two types of volume adjustment. A
manual turn knob on the bottom of the chassis (See Fig. 1, on Page 3)
allows you to control all the sounds in the system and a remote control
“RESET" option (Option # 6), allows you to control the volume level of the
car motor sounds remotely from the transformer. Turning the volume
adjustment knob clockwise will increase the volume and counterclockwise
will lower the volume of all sounds; bell, horn, engine sounds, TAS, etc.
USING “RESET" TO PROGRAM
PROTOSOUNDS®
As mentioned earlier, there are several programmable options in each
ProtoSound® equipped engine that can be remotely set from any
compatible standard AC transformer equipped with a whistle button. For a
list of compatible transformers, see the chart on page 28. This hands-off
approach gives you unprecedented control of your railroad empire’s motive
power never before seen in model railroading. Each programmable feature
can be accessed whenever your car is in the RESET state as described
earlier on page 4. By following the instructions below you will find the
programming easy and straight forward.
ENTERING RESET OPTIONS
ProtoSound® is equipped with a few programmable features that are
accessed in the RESET state by moving the transformer throttle up and
down between full voltage and low voltage (6 to 8 volts) without shutting
the transformer off
completely. Each time this
is done you advance, one
feature at a time, through
the available options. An
air-release sound is heard
each time the throttle is
advanced. In addition,
there are special sounds to
tell you what RESET position you are in.
For example, if you want to select Feature 2, you put the car in RESET,
and move the throttle up and down from full throttle to low two times.

After the second advance, you will hear two “clinks" indicating that the
computer is now in Feature 2. Advance the throttle again and you will hear
three “clinks" for Feature 3. Advance it two more times and you will hear a
“clank" indicating that you are now in Feature 5. Advance the throttle two
more times and you will hear a “clank" and two “clinks" indicating Feature
7. ((5 throttle advancements = 1 clank) + (2 throttle advancements = 2
clinks)). “Clank + “Clink" + “Clink" = Feature 7. You can advance the
throttle as quickly as you like (though you may not hear the air-release
sounds) and the computer will still remember the number of times the
throttle is advanced by playing back the number of “Clinks" and “Clanks"
to confirm the feature you’ve selected.
SETTING THE ENGINE VOLUME
Of all the sounds that come with each ProtoSound-equipped locomotive,
the one most often turned down is that of the engine volume because it is
the one sound normally
heard whenever the
engine is running and is
what usually can
become tiresome to the
ear over prolonged
running sessions. The
volume adjustment is
controlled through RESET Feature 6.
To access the feature, advance the transformer throttle to put the engine in
RESET. Move the throttle up and down, as described on page 5, 6 times.
After you hear the “clank” and “clink” indicating that you are in Feature 6,
press the whistle button to select the engine volume you desire. Pushing the
whistle button once will give you full volume, which is the factory setting.
Pushing the whistle button a second time will give you 50% volume,
pushing it a third time will give you 25% volume and pushing it a third time
will give you no sound. The microprocessor will immediately play the
sound level each time the whistle button is pushed so that you can decide if
it is acceptable. You can recycle through the four choices by simply
continuing to push the whistle button.
Once you have decided on the appropriate volume level, turn the
transformer throttle off and on again or press the transformer direction
switch to lock in your selection. The volume adjustment will remain set at
the level you have chosen until you change it again. Regardless of the
engine volume setting, the horn, bell, compressor and TAS sounds will

selections in Feature 6, when you select 0 volume, you can still hear the
horn, bell and TAS sounds when the engine is running or in neutral.
PROGRAMMING FOR A SEPARATE BELL BUTTON
CONTROLLER
To operate ProtoSounds® with
a separate bell button controller,
like the Lionel® No. 5906 bell
button, you will need to wire up
the controller to your
transformer and track as shown
in Fig. 2. Once the button is
wired, ProtoSounds® comes
preprogrammed to allow you to
operate the bell by simply
pushing the bell button once. To
turn the bell off, push the button
again. If the bell doesn’t function when you press the button, you may need
to re-program ProtoSounds to operate with a separate bell button controller.
To do this enter RESET
and go to Feature 20.
(See the sectionUsing
RESETToProgram
ProtoSounds®on page
13.) Once in Feature 20,
press the whistle button
and wait for the module
to sound a bell ding(s).
Continue pushing the whistle button until the module plays back two dings
(signifying that the module has been programmed for a bell button). Simply
turn the throttle off and then on again to “Lock-In" the new setting. To turn
the bell button function off, repeat the above procedure but keep pushing
the whistle button until the computer only responds with one bell ding.
PROGRAMMING FOR SQUEAKING BRAKE

whistle button again until
the module plays back two dings for option 2 - squeaking brakes are
activated for full-time operation, or press the whistle button again until the
module plays back three dings for option 3 -Squeaking brakes off. Once
you have decided on the desired setting, simply turn the throttle off and then
on again to “Lock-In” the new setting. To reset the computer to its original
factory default setting (option 2 - squeaking brakes are activated for
full-time operation), repeat the above procedure but keep pushing the
whistle button until the module only responds with two bell dings.
PROGRAMMING FOR HORN IN NEUTRAL
OPERATION
If you are operating your car with a separate bell button and want to blow
your horn when your car is in neutral, you will need to program
ProtoSounds® to do so as the factory setting only allows the horn to blow in
forward or reverse. To do this, enter RESET and go to Feature 25. (See the
section Using RESET To Program ProtoSounds® on page 13.) Once in
Feature 25, press the
transformer whistle button and
wait for ProtoSounds® to
sound a bell ding(s). Continue
pressing the whistle button
until ProtoSounds® sounds
two bell dings (signifying that
ProtoSounds® has been
programmed to sound the horn

in neutral). Turn the throttle off and then on again to “Lock-In" your
selection. Now, whenever you are in neutral, you can blow the horn with
the transformer whistle button. To reset ProtoSounds® to its original
factory setting of no horn in neutral, repeat the above procedure but keep
pressing the whistle button in Feature 25 until ProtoSounds® only dings
once instead of twice.
Note: When “Horn In Neutral" is set, the bell will only operate with a separate bell button and
the horn will not sound in neutral if the transformer throttle setting is over 11 volts.
PROGRAMMING FOR TAS OPERATION
ProtoSounds® is equipped with a RESET setting to automatically select
the Trolley Announcement Proto-Effects Options (TAS) features. You also
may want to configure TAS for manual operation or turn it off completely.
To configure TAS, enter RESET and go to Feature 28. (See the section on
Using RESET To Program ProtoSounds® on page 13). Once in Feature
28, press the transformer whistle button and wait for ProtoSounds® to
sound a bell ding(s). Continue pressing the whistle button on and off until
ProtoSounds® sounds one bell ding(s) (signifying that the TAS feature has
been turned off). Simply turn the transformer throttle OFF and then ON
again to lock in the new
setting. To reset
ProtoSounds® to its
original factory setting of
Squeaking Brakes and TAS
on, repeat the above
procedure but keep pressing
the whistle button in
Feature 28 until
ProtoSounds® dings 3
times instead of once. Interrupt the throttle by turning it OFF and then ON
again to lock in the new setting. If you prefer TAS Option 3 - Manual
Mode, repeat the above procedure but keep pressing the whistle button until
you hear 2 bell dings instead of 3.
ACTIVATING REMOTE LOCK-OUT CONTROL
ProtoSound® equipped engines feature a RESET setting that allows the
operator to remotely “lock” the engine into forward, neutral or reverse.
This is especially useful on layouts that feature “blocked” track sections.

The lockout feature comes from the factory in the OFF position, meaning it
is not active when you first take the engine out of the box. This is done to
prevent novice operators from accidentally locking their engine into
forward, neutral or reverse and then mistakenly thinking that the engine’s
electronics have failed. To activate the Remote Lockout Control setting, go
to RESET Feature 40 (See the section entitled Using RESET To Program
ProtoSounds® on page 13). Once in Feature 40, press the transformer
whistle button and wait for ProtoSounds® to sound a bell ding. Continue
pressing the whistle button
until ProtoSounds® sounds
two bell dings signifying
that the Remote Lockout
Control has been selected.
To lock in the setting,
simply turn the throttle all
the way off and then back
on again. To turn the
Remote Lockout Control setting back off, go back to Feature 40 and press
the whistle button until only one bell ding sounds. To lock in the setting,
simply turn the transformer throttle off and then back on again.
Alternatively, you can go to RESET Feature 18 to reset all ProtoSound®
features back to their original factory defaults including Remote Lockout
Control.
RESETTING ALL PROTOSOUND® OPTIONS TO
FACTORY DEFAULTS
ProtoSounds® is equipped with a RESET feature (Feature 18) that resets
all programmable options back to their original factory settings. This is a
useful feature if you find your engine not operating the way you think it
should and don’t want to take the time to check each RESET feature one at
a time. To reset all the RESET features back to their original factory
settings, enter RESET and go to Feature 18. (See the section entitled Using
RESETToProgram
ProtoSounds® on page 13).
Once in Feature 18, press the
transformer whistle button
and wait for ProtoSounds® to
sound a garbled bell sound.
Interrupt the throttle again to
lock in the setting.

REVERSE UNIT LOCK-OUT OPERATION
ProtoSounds® unique design eliminates the need for a lock-out switch on
the locomotive by allowing the customer to lock the engine into any
directional state (forward, neutral or reverse) from the transformer. This
will allow users to run the engine on layouts equipped with block signals or
stop stations which would normally cycle the engine back into neutral. The
feature must be first turned on by accessing RESET Feature 40 (See section
entitledUsing RESET To Program ProtoSounds® on page 13).
LOCKING THE ENGINE INTO FORWARD OR
REVERSE
To lock the engine into Forward or Reverse, use the transformer throttle to
enter Forward or Reverse (whichever state you want to lock the engine into)
and while the engine is moving press and hold the whistle button. WHILE
THE HORN IS BLOWING TURN THE THROTTLE OFF AND THEN
LET GO OF THE WHISTLE BUTTON. After about one second, you will
hear a short horn blast. QUICKLY TURN THE THROTTLE BACK ON
AGAIN. Your engine is now locked into Forward or Reverse and it will
remain so until you unlock the engine, even if you wait a year to run your
engine again.
UNLOCKING THE ENGINE
Unlocking the engine is a similar procedure. WHILE THE ENGINE IS
MOVING, PRESS AND HOLD THE WHISTLE BUTTON. WHILE THE
HORN IS BLOWING, TURN THE THROTTLE OFF AND THEN LET
GO OF THE WHISTLE BUTTON. After three seconds without power you
will hear one chime of the RESET bell. TURN ON THE POWER AGAIN.
Your engine is now in RESET and will operate normally once you interrupt
power and enter the forward direction.
LOCKING THE ENGINE INTO NEUTRAL
To lock the engine into the NEUTRAL position, PUT THE ENGINE IN
NEUTRAL AND WITH THE THROTTLE STILL ON, PRESS AND
HOLD THE WHISTLE BUTTON. WHILE THE WHISTLE BUTTON IS
BEING PRESSED, TURN OFF THE THROTTLE AND LET GO OF THE

20
RailKing PCC Street Car Operating Manual
WHISTLE BUTTON. After about one second, you will hear a short blast
of the horn. QUICKLY TURN THE POWER BACK ON AGAIN. Your
engine is now locked into NEUTRAL.
NOTE: When locking the engine in the Forward or Reverse positions, the whistle button will
blow the horn. But when locking the engine into the NEUTRAL position, the whistle button
may turn on or off sounds of the bell, coupler arming or coupler firing depending on the
transformer throttle voltage settings prior to the user’s attempt to lock out the engine.
Remember, the horn doesn’t blow in NEUTRAL (unless you programmed it to do so using
Feature 25. See page 17 for details), only the bell rings or the coupler operates in NEUTRAL.
While it doesn’t make any difference on how the lockout function operates, you may hear one
of the three different NEUTRAL-activated sounds.
To unlock the engine from the NEUTRAL position, follow the process to
unlock the engine in the Forward or Reverse directions above.
NOTE: When the car is locked out in forward or reverse, TAS operation is disabled.
MANUAL REVERSE UNIT LOCKOUT
(Non-ProtoSound® Equipped Engines)
Engines not equipped with ProtoSound® can be manually locked into
Forward, Neutral, or Reverse by sliding the lockout switch to the OFF
position after entering the desired reverse unit state (See Figure 1 on page
3). To operate the engine again in automatic mode, simply slide the switch
back to the ON position.
Note: Once the unit is locked out and an hour or more of non-use has passed, the reverse unit
may cycle into any of the three directional states. Should this occur, the ON/OFF switch
should be reset to the ON position to regain normal operation.
