TRANSFORMER OPERATIONS
Running your Atlas O loco with a Lionel/ Lionel-compatible transformer
1. Place your locomotive on Atlas O or compatible O gauge track.
2. Power up your loco with your transformer.
• Your loco is designed to operate on 8-18 volts alternating current. Virtually all Lionel and
Lionel-compatible alternating-current transformers are suitable.
• Do not power your 3-rail loco with direct current (DC). Damage to sensitive electronic
components may occur.
• When operating with a conventional transformer, the state in which your locomotive
starts up (neutral or forward) depends on the method by which the locomotive was
operated (conventional transformer or the TrainMaster Command system) the last
time that the locomotive was used.
When you operate your locomotive for the first time after taking it out of the box or if the locomotive
was last operated using the TrainMaster Command system, the locomotive will start up in neutral with
its headlights illuminated. When track power is briefly removed and then reapplied, the locomotive will
move forward.
If the locomotive was last operated using a conventional transformer and has been powered down for
at least five seconds, the locomotive will start up in forward at a speed dependent on the applied track
voltage.
3. Move ‘em out!
• Get your loco moving. Press the DIR button on your AC transformer. This will sequence the Lionel
reverse unit to the next operating state.
• Adjust track voltage until your locomotive moves at your desired speed. To increase speed,
increase track voltage. To decrease speed, reduce voltage. To stop the locomotive, cut track power.
• See page 5 for information on locking your loco in a single operating state.

Using your locomotive Electrocoupler in the non-Command environment
To use your loco’s Electrocoupler in the non-Command environment, you must first
couple a piece of rolling stock equipped with
traditional magnetic couplers directly to your
loco’s electrocouplers. The magnetic coupler on
the rolling stock will then react to the magnetic
field generated by a remote-control track sec-
tion (available separately). Place your rolling
stock’s coupler “trigger disc” over the central
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 loco’s electrocouplers will
NOT open manually or by using a
remote-control track section

the rear of your loco
Note!

To select a single operational state for your Atlas O loco (example: forward only), you can
deactivate the R4LC’s sequencing function with
the reverse unit control switch.
Get your locomotive moving in the desired direc-
tion, then slow it down without stopping. Set the
reverse unit control switch to PROGRAM. The loco
is now “locked” into your chosen direction. When
you no longer want single-direction operation,
just slide the reverse unit control switch back to
RUN.

Installing the Lionel no. 610-5906-001 sound activation button
To operate the bell and horn sounds when oper- ating your loco with conventional transformers
that do not have a horn or bell button, you’ll need
to install the Lionel no. 610-5906-001 sound acti-
vation button (available separately from Lionel).
Connect the button(s) as shown below.
The no. 610-5906-001 sound activation button (available separately) works with any Lionel
AC transformer except no. 6-4690 Type MW. Transformers made by other manufacturers
may not be compatible with Railsounds.
Note!

Lubricating your Locomotive
Help your Atlas O loco lead a long and produc- tive life on your railroad by maintaining it
properly.
Two basic rules to keep in mind: never over-
lubricate (a small amount will do), and avoid
getting grease or oil on the loco’s wheels or your
track. You’ll know your loco requires lubrication
when visual inspection reveals dryness on the
parts indicated in the illustration. Remove ac-
cumulated dirt and dust before lubricating, and
always lubricate any locomotive emerging from
prolonged storage.

Transformer (non-command) operations
Installing the RailSounds battery in your locomotive
This Atlas O Locomotive is equipped with Lionel
RailSounds®. Your loco features digital samples
from real-life diesel locomotives for the ultimate
in realism.
You may choose to install a 9-volt alkaline bat-
tery (included) in your loco. The battery ensures
interruption-free operation of RailSounds when
the locomotive is operated with a conventional
transformer.
However, if the locomotive is to be oper-
ated only with the TrainMaster® Com-
mand system, installing abattery is neither
necessary nor recommended.
The battery is located at the rear of the locomo-
tive. Remove the body by loosening the body
mounting screws. Refer to diagram on page 9.
NOTE! Please remove protective cover from battery clip.
NOTE! Although RailSounds is powered by track voltage, the battery is required for uninterrupted
operation and shutdown sequences when the locomotive is operated in non-command mode
with a conventional transformer. Use only Alkaline batteries.
NOTE! If RailSounds “drops out” during track power interrupts (direction change), replace the bat-
tery.

Your locomotive is equipped with a smoke generator that produces safe and clean white smoke during
operation.
Adding fluid to your locomotive’s smoke generator
NOTE! The locomotive is shipped with the smoke unit turned off and with very little
smoke fluid in the smoke generator.
There is a smoke unit control switch that is marked
SMK/NO SMK, as shown in the diagram on page
10. If you prefer to have a smoke-free locomotive,
leave the switch set at its NO SMK position.
If you wish to use the smoke unit, before filling
the smoke generator, move the smoke unit control
switch from the NO/SMK to the SMK postion. To fill
the smoke generator, first remove the hatch from
the top of the long hood. Then add 15 to 20 drops
of Lionel or Lionel compatible smoke fluid to the
loco’s smoke fluid funnel. Refer to diagram below.
If no smoke comes out of the exhaust stackafter
you have filled the smoke unit and run the loco
for 20 or more seconds, there is probably a vapor
lock in the smoke generator. To clear this vapor
lock, simply blow gently down the exhaust funnel.
To protect the smoke generator from overheating,
the smoke unit will automatically turn itself off
when the smoke fluid is empty. To refill an empty
smoke generator, add another 15 to 20 drops of
smoke fluid to the loco’s funnel.
When using command control, you can increase
the speed at which the smoke generator heats up
by using the CAB-1 remote. First press AUX1 and
then press and hold the 9 key to speed heating of
the smoke generator. Do not hold down the 9
key for more than 15 seconds.

With Railsounds, you experience the sounds of real railroading like never before.
Simply put, it’s the most sophisticated, authentic
model railroad sound system in the world.
• Four diesel-roar levels. Your loco’s speed
determines the level of diesel RPM roar—au-
tomatically, if you prefer: idle, half throttle,
three quarters or full-speed output.
• MultiHorn™. A different horn sound
at different speeds—a Railsounds
exclusive.
• Mechanical bell. Press BELL on your trans-
former to begin the effect, again to discontinue.
• Reverse unit reset sound. Power down
your track, wait for 3-5 seconds, and listen for
the air-release sound—that’s the loco telling
you its Lionel Command reverse unit has just
reset to forward operation.
• Shutdown sequence. No other model rail-
road sound system shuts down like Railsounds.
Turn off track power, and after the air-release
reset sound, you have two seconds to restart
your loco. If you’re done with operations,
Railsounds will commence with a realistic
diesel shutdown sequence about two seconds
after the air-release reset occurs.
• For even more authentic Railsounds
effects, operate in the TrainMaster Command
environment.
Experiencing the range of your locomotive’s Railsounds system
Notes on Railsounds
• Turn the volume knob clockwise or counter
clockwise in the location shown on page 6 to
adjust sound output.
• Listen for incidental locomotive sounds during
Railsounds operation. They’re automatic
and, of course, authentic.
• The 9-volt alkaline battery you installed
ensures continuous loco diesel roar in conven-
tional operation.
• Longer track-power interruptions (including
locomotive derailments) cause Railsounds to
shut down after about 7 seconds.
