Running your Lionel PA-1 set with a Lionel transformer
Place your PA-1 set on Lionel or Lionel-compatible
O gauge track.
• Your PA-1 will operate on most 031 radius track configurations. We
recommend 042 radius minimum for best performance.

3Move ‘em out!
• Get your PA-1 set moving. Press the DIR button on your CAB-1 remote or
Lionel transformer. This sequences the Liontech Command reverse unit (R2LC)
to the next operating state. The R2LC alternates between three states: forward,
neutral, and reverse.
• Adjust track voltage until your PA-1 set moves at your desired speed. To
increase speed, increase track voltage. To decrease speed, reduce voltage. To stop
the locomotive set, cut track power.
• To select a single operating state (example: forward only), you can deacti-
vate the R2LC’s sequencing function. Get your PA-1 set moving in the desired
direction, then slide the reverse unit control switch on the powered PA-1’s under-
side to PROGRAM (PGM). See page 15 for the switch location and positioning.

• Your PA-1 set is designed to operate on 7-18 volts alternating cur-
rent. Virtually all Lionel and Lionel-compatible alternating-current transform-
ers are suitable; we recommend the TrainMaster Command model railroad con-
trol system.
• Do not power your PA-1 set with direct current (DC). Damage to sensi-
tive electronic components may occur.
• When you first power up your track, the PA-1 set will wait between
3 and 8 seconds as it “listens” for digital language from the TrainMaster
Command Base (available separately). When it’s determined that it’s on a con-
ventional (non-Command) railroad, both PA-1’s headlight and cab light will
illuminate and the non powered PA-1’s RailSounds will fire up. At this point, the
PA-1 set is in neutral. (This occurs when placing the PA-1s on your railroad for
the first time. Thereafter, they start in forward after every three-second power
interrupt.)

To use your powered and non-powered
PA-1 set ElectroCouplers in the non-
Command environment, you must first cou-
ple a piece of rolling stock equipped with
Lionel magnetic couplers directly to your
powered and non-powered PA-1 set. The
magnetic coupler on the rolling stock will
then react to the magnetic field generated
by a Lionel remote-control track section
(available separately). Place your rolling
stock’s coupler “trigger disc” over the cen-
tral coil of a remote-control track section
and press uncouple on the controller. The
magnetic field pulls the disc downward, and
the coupler opens.

Your PA-1’s RailSounds system—the basics
Lionel RailSounds is the most realistic
model railroad sound sys-
tem in the world. Your
PA-1 features digital sam-
ples from an authentic
PA-1 for the ultimate in
realism.
Begin by installing a
9-volt alkaline battery in
the non-powered PA-1
unit. This ensures inter-
ruption free operation of
RailSounds. Remove the
six screws on the under-
side of the frame and lift
the body up. (see page 20)
Connect the 9-volt battery
to the battery clip and
stand the battery in the bracket as shown.
Replace the body and reinsert the screws.
Apply track power and the PA-1’s
RailSounds system deliv-
ers an authentic start-up
sequence, followed by
sounds of the locomotive
at idle. As the PA-1’s speed
increases, the RPMs move
through four levels of
roar. Sounds return to idle
only after the locomotive
has come to a complete
halt. To silence diesel
RPM roar (horn and bell
remain unaffected), slide
the RailSounds (RS)
switch to its OFF position
before powering up the
locomotive. See page 16
for the non-powered PA-
1’s switch location and
positioning. To return to the diesel RPM
roar, return the switch to the ON position,
before powering up the locomotive.
Install a 9-volt alkaline battery in your
non-powered PA-1 unit. Remove the
body, and connect the battery to the clip
and bracket. Then reinstall the body on
the frame.
Note!
Note!
Note!
Transformer operations
Although track voltage powers RailSounds, the battery is required for uninterrupted
operation and shutdown sequences. Use only alkaline batteries; do not use “heavy
duty” batteries.
Discontinue locomotive power for 10 seconds before changing the RailSounds
on/off switch.
If RailSounds “drops out” during track power interrupts, replace the battery.

Transformer operations
With RailSounds, you experience the sounds of real railroading like never
before. Simply put, it’s the most sophisticat-
ed, authentic model railroad sound system
in the world.
• Four diesel-roar levels. Your PA-1’s
speed determines the level of diesel RPM
roar—automatically, if you prefer:
idle, slow, medium, or full-speed output.
• MultiHorn™. A different horn sound
every time—a RailSounds exclusive.
• Mechanical bell. Press BELL on your
CAB-1 or transformer to begin the effect;
again to discontinue.
• Full control of RPMs. Prefer hands-
on control of diesel RPM roar? Want to
“ramp up” RPMs before pulling out, just
like real diesels do? It’s easy with
RailSounds. Place your PA-1 set in neu-
tral and increase track voltage to maxi-
mum. RPMs will continue to increase as
long as the PA-1 remains in neutral,
eventually reaching their highest level.
Now, decrease track voltage to the desired
speed level. Press DIR on your CAB-1
remote or transformer, and head out
with your PA-1 at full churn, just like the
real thing. RPMs will remain at that
level until the locomotive has come to
a complete halt. Experiment with con-
trollable RPMs—it’s a blast!
• Reverse unit reset sound. Power
down your track, wait for 3-5 seconds,
and listen for the air-release sound—
that’s the PA-1 set telling you its
Liontech Command reverse unit has just
reset to forward operation.
• Shutdown sequence. No other model
railroad sound system shuts down like
RailSounds. Turn off track power, and
after the air-release reset sound, you
have 2 seconds to restart your PA-1. If
you’re done with operations, RailSounds
will commence with an authentic PA-1
shutdown sequence about 2 seconds after
the air-release reset occurs.
Experiencing the range of your PA-1’s RailSounds system
Notes on RailSounds
• Use the non-powered PA-1 unit’s frame-
mounted volume control to adjust sound
output. (See page 16 for its location.)
• Listen for incidental locomotive sounds
during RailSounds operation. They’re
automatic and, of course, authentic.
• The 9-volt alkaline battery you installed
ensures continuous PA-1 diesel roar.
• Longer track-power interruptions
(including locomotive derailments)
cause Railsounds to shut down after
about 7 seconds.
• For even more authentic RailSounds
effects, operate in the TrainMaster
Command environment.
Battery must be installed for shutdown sequence

Transformer operations
Your PA-1’s Odyssey System™
You can lock your PA-1 into speed control mode (ideal for low speed operation) so
it will automatically compensate for grades,
or to simply maintain a specific speed set-
ting. To turn on the speed control, get your
PA-1 moving at the desired speed, in for-
ward or reverse. Let it run at the desired
speed for at least 5 seconds. Press and hold
the horn/whistle button for 2-3 seconds as
you increase the throttle by at least 3 volts.
Your PA-1 will accelerate briefly, then will
return to your set speed once you release the
horn/whistle button. As long as the throttle
position is maintained at a higher setting
than the initial level, your engine will
maintain a constant speed. If the throttle is
turned below the original level, your PA-1
will slow down due to the available voltage
decrease below the “set” level. To check if
the speed control setting has been “accept-
ed”, ease up the throttle. You will see the
lights brighten, but the speed will remain
constant. For best results, adjust the track
voltage about 3-4 volts above the “set”
point. This will provide enough spare volt-
age to compensate for uphill grades, etc.,
but will prevent excessive voltage to the
lamps and smoke unit. (In conventional
mode, these operate at track voltage, and
excessive voltage may lead to premature
bulb burn-out.)
* If you wish to change the speed control
setting, you must deactivate the speed
control, then reactivate at the new
setting.
To turn speed control off, get your PA-1
into neutral for at least 5 seconds. Press the
horn/whistle for 2-3 seconds while lowering
the throttle voltage by at least 3 volts. Do not
turn throttle to off, or speed control may not
deactivate. This can be difficult if you have
established a low speed control setting. Once
you are in neutral, you can increase the
track voltage before pressing the horn/whis-
tle button and lowering the voltage. This
will give you more “room” to lower the volt-
age. (The speed control deactivates when it
sees a -3 volt change with horn/whistle
pressed, regardless of initial voltage level.)
Note! Speed control settings are retained in memory even if power is turned off.
They will remain present until deactivated.

Adding fluid to your locomotives’ smoke generators
Your locomotives are equipped with smoke generators that produce safe,
clean white smoke during operation.
All smoke generators require the periodic
addition of Lionel smoke fluid in order to
function. Pierce the tube end with a pin,
then add 20-25 drops of fluid into each
Locomotive’s stack. Smoke production will
commence momentarily, faster if you run
your locomotive at speed. When smoke
production wanes, add more fluid (four to
eight drops).
If you prefer to have smoke free
locomotives, there is a switch located on the
bottom of each engine near the fuel tank
marked SMK/NO SMK (see page 15/16 for
location). Move the switch to NO SMK and
your locomotives will stop smoking.
When the smoke unit is on, always keep
a small amount of smoke fluid in the
locomotives’ smoke generators; the
generators’ elements can become damaged
if operated without fluid. Smoke production
is greater at higher voltages and when the
locomotives are pulling a heavy load or long
consist.
For best results, power should be turned
off when you are adding smoke fluid. If any
fluid stays in the smokestack, it may be
necessary to gently blow into the stack
opening to force the fluid through.
NOTE: When you are in neutral (conven-
tional mode only), the smoke units will
pulsate on and off to prevent overheating of
the element.

TrainMaster Command operations
The Command control environment
Lionel TrainMaster Command is the advanced model railroad control system
from Lionel. Both of your PA-1s are
equipped with R2LC’s for digital control of
all features. TrainMaster Command gives
you the power to operate multiple
Command-equipped locomotives on the
same track, at the same time.
To operate in Command, you
need a Command Base and a CAB-1
remote. Find them both at your authorized
Lionel retailer.
Place your PA-1 set on Lionel or Lionel-compatible
O gauge track.
•Make sure track power is OFF before placing them on the track.
• Make sure your Lionel Command Base is ON and its communications
wire is connected to the COMMON post on your Lionel transformer or the U on
any of your installed PowerMasters.
• Once positioned on the track, increase track voltage to FULL (on
PowerMaster, slide the CMD/CONV switch to CMD).
Address your PA-1 set using CAB-1.
• Press ENG and 1 on the numeric keypad of your CAB-1 remote. This
command is sent by CAB-1 to the Command Base, which then translates
your command into digital code. That code is sent around your railroad’s
outside rails in the form of a digital “halo.” All Command-equipped
Lionels listen to this digital communication, but they do not respond until
they hear their individual ID number—in this case, “1.”
• The digital language of TrainMaster Command—and not track power—
controls the actions of Command-equipped Lionels. Track power is simply
like gasoline in the tank of your car—it gives you the power to go places,
but it doesn’t tell you where to go or how fast to get there.
• All Command-equipped Lionels come factory-programmed
with an ID# of “1.” To change the ID#s of both your powered PA-1 unit
and non-powered PA-1 unit (both equipped with R2LC), see page 15.
Move ‘em out!
• Throttle up or press any command button on CAB-1. Your PA-1 set will
respond to your every command. Read on.

Tuning your PA-1’s performance
MOMENTUM
TrainMaster Command’s momentum
feature simulates the labored performance
of a locomotive pulling a heavy load. Press
L, M, or H (located under CAB-1’s removable
panel) for light, medium, or heavy momen-
tum. The PA-1’s R2LC remembers this set-
ting until you change it. For quick loco-
motive response, choose L.
BRAKING AND BOOSTING
There’s more to starting and stopping
than just turning the CAB-1 throttle. Use the
BOOST and BRAKE command buttons—
they give you incremental control of speed
and are the superior way to handle grades,
gradual stops-and-starts, and more. Plus,
using BRAKE in the Command environment
gives you a bonus RailSounds effect—the
ultrarealistic sound of squealing brakes.
SOUND QUALITY
To achieve your preferred RailSounds
master volume level, we recommend you use
your non-powered PA-1 unit’s frame mount-
ed volume control dial (see page 16 for
location). Turn the dial left or right to
adjust the volume to your liking.
For quick remote-control of volume
below the master setting—for example,
muting—use the CAB-1 numeric keypad’s
volume control. Press AUX1 and then 4 on
the numeric keypad to lower overall
Railsounds output.
HIGH VOLTAGE SETTING
Press SET, headlight will flash. Get your
locomotive moving to the maximum speed
you want it to run, press BOOST. Use this to
keep your locomotive from excess-speed
derailing. Turn off the high voltage setting
by pressing SET, then BOOST, holding each
for one second.
STALL
Make your PA-1 feel more responsive by
setting a “stall” voltage. Get your locomo-
tive moving, then press SET; the PA-1 will
stop. Turn the throttle clockwise to get the
locomotive moving, then decrease speed
until the locomotive just stops. Then press
SET again; the R2LC remembers the stall
setting until you change it. To clear stall,
press SET twice, holding it for one second
each time.
Note! These settings will be lost when you assign new engine ID#s.
Speed control in command mode is auto- matic. Simply adjust the speed to desired level, and the Odyssey System will maintain it through grades, etc.

Building lash-ups
When real railroads operate two, three, or even four locomotives together, they call
it a “lash-up.” A lash-up is railroading’s
answer to steep grades, long trains, and extra-
heavy loads.
In the TrainMaster Command system,
lash-ups are addressed as “TRAINS” -the TR
button on CAB-1. When you build lash-ups
with TrainMaster Command, several engines
are grouped under a single TR ID#. Lash-up
building should be attempted only after
you’ve mastered ordinary TrainMaster
Command operations.
Pick the locomotives in your lash-up and
move them together (but don’t couple them)
using ENG and each one’s ID#. Because CAB-
1’s TR .button also means ”TRACK” for
PowerMaster control, select a TRAIN (TR) ID#
that is NOT a number identifying PowerMaster
TRACKs. For example, if you’re using four
PowerMasters and have named their TRACKs
1,2,3, and 4, choose a number between 5 and
9 for your TRAIN ID#.
Finally, make certain the locomotive’s
direction switch is on RUN. Perform a loco-
motive reset (AUX1, 0) to see what the loco-
motive’s first-start direction is. It’s possible to
have a “contrary”locomotive that’s simply fol-
lowing the direction of the reverse unit con-
trol switch.

will only be produced by the front
engine in a “train”. (This is why your
non-powered PA-1 should be pro-
grammed as the front engine.)
Now all engines respond togeth-
er when you address them as
Train #? (the train number you
select)
If an engine is out of sync after a
TR reset, read “lash-up
troubleshooting” on page 26 of
your TrainMaster instruction
manual.
It‘s still an ENGINE. Whenever a
locomotive is in a “TRAIN”, you
can still individually address it (using its ENG
ID#) to adjust lighting, open individual cou-
plers, and tune performance.
Note!
You may establish momentum, high voltage or stall settings for the entire
“TRAIN” similarly to an individual engine (see page 14). Setting momentum,
high voltage or stall settings in “TRAIN” mode overrides any previous individual
“engine” settings. Conversely any “engine” settings will remain present even in
“train” mode unless they are overridden. For best results and fewer required steps,
these setting should be done in”TRAIN” mode if you intend to run the units as a
lash-up.

Replacing your powered/non-powered PA-1 unit’s lamps
Your PA-1 units are both illuminated by two 14-volt lamps. One illuminates the
headlamp and the other illuminates the cab
interior. During the course of normal opera-
tion, they may require replacement.
Start by separating the plastic body shell
from the frame; remove the six screws on the
underside of the frame and lift the body up.
Each lamp rests in a holder, with its
prongs plugged into a socket. Carefully pull
the bulb straight up out of the holder to
remove it. Replace the expired lamp with
Lionel part no. 610-8049-300, available
from your local Lionel Authorized Service
Center or Lionel Service. (For more informa-
tion, see Lionel Service on page 24.)
Insert the replacement lamp’s prongs
into the socket, making sure of a tight con-
nection. To reinstall the shell, line up the
screw holes on the frame and body shell, and
reinsert the screws. Make sure all of the wires
are inside the body before you tighten the
screws.
