OPERATING INSTRUCTIONS
Thank you for purchasing the MTH Electric Trains die-cast 263E steam
locomotive. This reproduction of the famous 263E locomotive measures
over 20” in length and weighs over six pounds. The locomotive is capable
of operating on O-31 3-rail track with any compatible AC transformer, (see
page 34 for a complete list of compatible transformers and wiring
instructions) and is completely compatible with most other 3-rail
locomotives, rolling stock and accessories.
The locomotive and tender are equipped with several deluxe features that
are simple and fun to operate. Each feature is described among the
following pages which should be read before the engine is operated. For
those of you who can’t wait to get started, the Quick Start Operating
Instructions, found on page 3, should be read so that you understand the
basics of the operating system.

QUICK START - BASIC OPERATION
The MTH 263E contains state-of-the art electronics with several built-in
automatic features for incredibly realistic operation. Despite these advanced
features, the 263E is easy to operate with any compatible standard AC
transformer (see the compatibility chart on page 34). All models are
equipped with an operating smoke system that should be primed with
smoke fluid before operating. Adding 15 - 20 drops of fluid through the
smoke stack should be sufficient. If you choose to not prime the units with
fluid,turn the smoke unit switch located under the trailing truck to the
OFF position. This will prevent any damage from occurring to the smoke
unit when running the engine without a primed smoke unit. For more
information see the section on page 4 on Smoke Unit operation.
The 263E model is 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. Before
the engine can be operated however,
the reverse unit plug that extends out
of the tender must be inserted into
the receptacle at the back of the
boiler cab as seen in Figure 1. Once
the plug is inserted, the throttle on the transformer can be advanced. You
will see that only the engine’s lights come on and that on ProtoSound
equipped engines, two dings from the sound system will chime followed by
the steam compressor pump sounds. The engine does not run. This is
known as the RESET state and is explained in more detail beginning on
Page 5. The ProtoSound® DCRU® will not power the motor until the
throttle is turned OFF and then ON again. At this point, the engine will
now function just like any other electronic or mechanical E-unit.

PROTOSMOKE™ UNIT OPERATION
The 263E contains a self-powered smoke unit that outputs a steady stream of smoke through
the smoke stack on the roof of the engine. The ON/OFF switch located next to the trailing
truck must be in the ON position in order for the smoke unit to function. See Fig. 2 below.
The smoke unit is essentially a small heating
element and wick which soaks up and then cooks" a
mineral oil-based fluid that omits a harmless smoke.
The smoke is then forced out of the stack via a small
electric fan which runs at a constant speed. However,
the smoke intensity can be varied by increasing the
transformer voltage setting. The higher the setting,
the more intense the smoke output.
For best results, we recommend that you add 15 -
20 drops of ProtoSmoke, Seuthe, LGB or LVTS
fluid before you run the engine. If you dont choose
to add the fluid, then the smoke unit switch should
be turned off. Failure to either add the fluid or turn the switch off could lead to damage to the
smoke unit heating element and or wicking. Add the fluid through the smoke stack hole as
indicated in Figure 3. After adding the fluid, gently blow into the stack to eliminate any air
bubbles. Do not overfill the unit as overfilling can cause the fluid to leak out and coat the
interior engine components. When the smoke output begins to diminish while running the
engine, an additional 10-15 drops of smoke fluid should be added or the smoke unit switch
should be turned off. When storing the engine for long periods of time, you may want to add at
least 15 drops of fluid to keep the wick soaked with fluid and prevent it from drying out. After
removing the engine from storage, it is advisable to add another 25 drops of fluid, letting the
wick soak up the fluid for 15 minutes prior to operation.
SMOKE UNIT MAINTENANCE
CAUTION: Operating the engine without smoke
fluid and with the smoke unit switch in the ON
position can damage your smoke unit wick, causing
the wick to become hard, blackened and
unabsorbant around the heating element. When this
occurs, it may be difficult for the wick to soak up
the smoke fluid resulting in poor or no smoke
output. If that occurs, we recommend that you
inspect and/or replace the wick taking care to not
run the engine without fluid in the future. You can
inspect the wick to see if it needs replacement by
removing the smoke unit inspection cover from the
body as seen in Fig.4. After removing the chassis
and inspection cover screws lift the inspection plate
away and inspect the wick. If the wick is darkly discolored and hard, it should be replaced.

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 engine is controlled by a
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
locomotive 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 engine first enters
RESET, the microprocessor initiates a system check to determine if the
system, transformer and engine are operating correctly. This takes
approximately 2.2 seconds during which you will hear the engine’s startup
sounds begin. In order for ProtoSounds® to properly initiate the system

check, do not advance the transformer throttle past 10 volts when you first
enter RESET, wait for the diesel startup sounds to begin and 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
remote Steam Chuffing Volume Adjustment, Separate Bell Button
Operation (pre-programmed at the factory), Whistle In Neutral Operation,
ProtoCoupler™ On/Off Control, Squeaking Brakes and Passenger Station
or Freight Yard Proto-Effects. Each of these features are described in more
detail later. You will notice that when in RESET, your engine 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 locomotive using any of these
programmable features, simply leave RESET and wait 2.2 seconds before
interrupting the power to put the engine in forward. After you leave
RESET, your engine will operate normally in all the direction states of
forward, neutral and reverse. Remember though, once power is turned off
for more than 3 seconds, the next time power is applied to the track, your
engine will be back in RESET.
WHISTLE OPERATION
Your 263E ProtoSound-equipped engine is equipped with a digital
recording of a steam whistle. The whistle sound can be activated anytime
the engine is in forward or reverse by pressing the whistle button on your
transformer. The whistle will continue to blow as long as the whistle button
is depressed. The whistle will not function in RESET and must be
configured through a RESET option to allow the whistle to work when the
engine is in neutral. See page 21 for information on whistle programming
in the Using RESET To Program ProtoSounds® section of this manual.
BELL OPERATION
Your 263E ProtoSound-equipped engine is equipped with a digital
recording of an actual steam engine bell. The bell can be turned on or off
with any separate bell button, like the Lionel® Railsounds® No. 5906 Bell

MTH 263e Operating Manual
TINPLATE
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 engine 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 engine is cycled into forward or reverse until you press 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 train, the next time you run the
engine, 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 engine enters one
of the three directional states.
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 (any higher voltage will arm the ProtoCoupler™) 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
engine, simply interrupt the power with the transformer throttle or the
transformer directional switch and enter forward or reverse.
ENHANCED NEUTRAL STEAM SOUNDS
The enhanced Neutral Sounds can be automatically heard whenever the
engine is in neutral. The sounds, which include Steam Pop-Off, Steam
Blow-Down, and Steam Injector sounds occur every 2 to 30 seconds. Each
of the three sequences will play at random intervals to eliminate repetitive
and boring sequences. While the sounds are selected to play randomly by
the microprocessor, there is no guarantee that you won’t hear the same
message repeated twice or more times.
SQUEAKING BRAKE SOUNDS
ProtoSound equipped engines feature the ability to play the sound of
squeaking brakes whenever your engine slows in speed. There are two
settings for activating the squeaking brake sounds. The default setting
allows the brake sounds to play while the engine 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 second setting requires that a bell button be
used to “arm” the brake feature and is explained in more detail in the
“Activating Passenger Sounds” section found 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
required to synchronize the
playing of the brake sounds with the movement of the engine. It is not
uncommon for the engine 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 engine 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 quickly 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 an engine 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 engine may continue to play the brake sounds once your engine
comes to a stop or that the sounds stop prematurely before the engine comes to
a complete halt. For example, if you simply run the engine and turn the
throttle off quickly, the brake sounds will likely continue playing even though
the engine 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 engine moving while the
brake sounds play and then turning the throttle off just as the sounds stop.
Remember that once you stop the engine, you should turn the throttle to the off
position if you dont want to activate the Passenger Sounds feature described
later in this manual.
The ProtoSound squealing brake feature also has the ability to simulate the
squeal of wheel flanges when your train enters a curve at high speeds. The
same brake squealing sound plays, but you dont need to reduce the
transformer throttle to activate the squealing sounds. To play the squealing
sounds as wheel flange sounds, trigger the brake feature using either method 1
or 2 above. Once triggered set the transformer throttle setting at 14 volts or
higher. As your engine enters a curve (or anywhere on the layout) quic[ky
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 engine wont slow down even
though the sounds play. This simulates the wheel flange squeal of a train
travelling through a turn too quickly.
Note: Consistent activation of the wheel flange squealing is determined by the
condition of your transformers whistle button rectifier disc. Older rectifier
discs may need to be replaced in order to play squealing sounds.

PASSENGER ANNOUNCEMENTS (PFA)
ProtoSounds is now equipped with operator controlled passenger station
announcements, hereby known as PFA. This easy to use feature plays
digitally reproduced passenger station sounds whenever your engine stops
at a train station on your layout. No additional wires or modifications are
needed on your layout to enjoy these amazing sound effects. 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 PFA 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 PFA
sequence is designed to simulate the arrival, disembarking, embarking, and
departure of a train entering and leaving a train station. The sounds include
public address arrival and departure messages, passenger disembarking and
embarking sounds, conductor voices and general train station ambient
sounds. Each is described in more detail in the following sections.
ACTIVATING PASSENGER SOUNDS
Your ProtoSounds equipped engine features an operator controlled
passenger station sound set. Once activated, this easy to use feature plays
digitally reproduced sounds of a passenger station whenever you stop your
engine in the neutral position at a train station on your layout.
ARMING THE PASSENGER SOUNDS FEATURE
Before the passenger station sounds can be heard, ProtoSounds must
activate the feature so that the next time the engine enters the neutral
position, the sounds can play, The feature can be activated one of two ways.
Option 1: 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
pressing and holding the
bell button for three
seconds or longer (it
doesn’t matter if you are
in forward, neutral or
reverse). You will hear
