Transformer operations
Running your Lionel 726 Berkshire with a Lionel transformer
Place your 726 Berkshire on Lionel or Lionel-
compatible O gauge track.
• With track power OFF, connect the locomotive tether between
the engine and tender. The six-pin tender plug connects with the
six-pin recepta-
cle on the loco-
motive. Feed
any excess teth-
er into the ten-
der. Connect
the drawbar
between loco-
motive and
tender.

2Power up your 726 Berkshire with your transformer.
• Your 726 is designed to operate on 5-15 volts alternating current.
Virtually all Lionel and Lionel-compatible alternating-current
transformers are suitable; we recommend the TrainMaster
Command model railroad control system.
• O NOT POWER YOUR 726 WITH IRECT CURRENT (DC). Damage to
sensitive electronic components may occur.
• When you first power up your track, the 726 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 transformer-controlled railroad, the 72 ’s
headlight will illuminate and Railsounds will fire up. At this point,
the 72 is in neutral. (This occurs when placing the 72 on your rail-
road for the first time. Thereafter, it starts in forward after every
three-second power interrupt.)
Note!

3Move ‘em out!
• Get your 726 moving. Press the DIR button on your CAB-1 remote
or Lionel transformer. This sequences the Liontech Command
reverse unit (LCRU2) to the next operating state.
• Adjust track voltage until your 72 moves at your desired speed.

o select a single operational state for
your Lionel 72 Berkshire (example:
forward only), you can deactivate the
LCRU2’s sequencing function with the
reverse unit control switch, located
underneath the cab of the 72 .
Get your locomotive moving in the
desired direction, then slow it down
without stopping. Set the reverse unit
control switch to PROGRAM/LOCK.
The 72 is now “locked” into your cho-
sen direction.
When you no longer want single-
direction operation, just slide the
reverse unit control switch back to

Your 726 Berkshire’s Railsounds system—the basics
L
ionel Railsounds is the most realistic
model railroad sound system in the
world. Your 72 features digital samples
from a real-life Berkshire for the ultimate in
realism.
Begin by
in-stalling a
9-volt alka-
line battery
in the ten-
der. This
ensures full-
feature
operation of
Rail-
sounds. The
battery
compart-
ment is
located
beneath the
tender’s removable coal load. Connect
the 9-volt alkaline battery to the lead
and replace the coal load.
When you first apply track power, the
72 ’s Railsounds system produces
sounds of the locomotive at rest. As the
72 moves, chuffing begins, increasing
with the locomotive’s speed.
To silence
the steam
chuffing
(whistle/bell
are unaffect-
ed), slide the
Rail-sounds
switch, locat-
ed under the
tender, to the
OFF position
before power-
ing up the
locomotive.
The whistle is
activated by
using the
lever or button on your transformer or
CAB-1. The circular hatch on the tender
serves as the volume control dial to
raise or lower the level of sound.
Installing a 9-volt alkaline battery in your 7 6
Berkshire’s tender.
Volume control dial
Although Railsounds is
powered by track voltage,
the battery is required for unin-
terrupted operation. Use
only alkaline batteries.
Note!
Discontinue locomotive
power for 10 seconds before
changing the Railsounds
ON/OFF switch position.
Note!
If Railsounds “drops out” dur-
ing track power interrupts
(direction change), replace the
battery.
Note!

W
ith 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. And
remember—inside your Lionel 72
Berkshire are the sounds of a real-life
Berkshire. No other electric train can
offer you authentic Berkshire sounds.
That’s the power of Lionel.
• Variable chuff rate. Your 72 ’s speed
determines the steam chuff rate.
• MultiWhistleTM. Different whistles
every time—a Railsounds exclusive.
• Authentic bell. Press BELL on your
CAB-1 or transformer to begin the
effect, again to discontinue. Even the
final “hit” is muted like the real thing.
• Reverse unit reset sound. Power down
your track, wait for 3-5 seconds, and listen
for the air-release sound—that’s the 72
telling you its Lionel 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
two seconds to restart your 72 . If you’re
done with operations, Railsounds will
commence with an authentic Berkshire
shutdown sequence about two seconds
after the air-release reset occurs. Note: The
9-volt battery must be installed for the
shutdown sequence to occur (see page 5).
Experiencing the range of your 726 Berkshire’s Railsounds system
Notes on Railsounds
• Use the tender-top “water hatch” vol-
ume control to adjust sound output.
• Listen for incidental engine sounds
during Railsounds operation. They’re
automatic and, of course, authentic.
• The 9-volt alkaline battery you installed
ensures continuous Berkshire sounds, even
during short track-power interrupts.
• Longer track-power interruptions
(including locomotive derailments)
cause Railsounds to shut down after
about 7 seconds.
• For even more authentic Railsounds
effects, operate your 72 in the
TrainMaster Command environment.
See page 8 for details.

TrainMaster Command operations
Your 726 Berkshire in the TrainMaster Command environment
L
ionel TrainMaster Command is the
fun and sophisticated model railroad
control system from Lionel. Your 72
Berkshire features the Lionel Command
reverse unit, which acts as both a con-
ventional reverse unit as well as the key
to unlocking many extra features when
you operate in Command mode.
TrainMaster Command gives you the
power to operate multiple Command-
equipped locomotives on the same track,
at the same time. It’s the most fun you
can have with electric trains, and it’s
incredibly easy too! Just follow the
directions below and you’ll be on your
way.
TO OPERATE IN COMMAN , YOU NEE A
COMMAN BASE AN A CAB-1 REMOTE.
Find them both at your authorized
Lionel retailer.
Place your 726 on Lionel or Lionel-compatible
O gauge track.
• Make sure track power is OFF before placing it on track.
• Make sure your Lionel Command Base is ON and its communi-
cations 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). This auto-
matically delivers full voltage to the track.
2
2Address your 726 with 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 communica-
tion, but they do not respond until they hear their own ID number.
• 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 I # of “1.” To change your 72 ’s ID#, see page 11.

3Move ‘em out!
• Throttle up or press any command button on CAB-1. Your 72 will
respond to your every command. Read on. The fun is just beginning!

ing relaxes to a more sedate sound, as
though the load placed on the 72 has
decreased. Experience DynaChuff on
steep grades, at yard crawls, and at

Tuning your 726 Berkshire’s performance
MOMENTUM
Simulate the labored performance of
a locomotive pulling a heavy load with
momentum. Press L, M, or H (located
under CAB-1’s removable panel) for
light, medium, or heavy momentum.
The LCRU2 remembers the setting until
you change it. For delayed response,
use H. For quick response, choose L.
BOOSTING AND BRAKING
Use the BOOST and BRAKE com-
mand buttons for incremental control
of speed and a superior method for han-
dling grades, stops-and-starts, and
more. Plus, using BRAKE in the
Command environment gives you a
bonus Railsounds effect—the ultrareal-
istic sound of squealing brakes.
STALL
Make your 72 feel more respon-
sive by setting a “stall” voltage. Get
your locomotive moving, then press
SET; the 72 will stop. The headlight
will flash, indicating it’s in the SET
mode. Turn the throttle clockwise to
get the engine moving, then decrease
speed until the locomotive just stops.
Then press SET again; the LCRU2
remembers the stall setting until you
change it. To clear stall, press SET
twice, holding it for one second each
time.
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 accidentally
being derailed. To clear the setting,
press SET, then BOOST without
moving the throttle.
SOUND QUALITY
To achieve your preferred Rail-
sounds master volume level, use the
tender-top water-hatch volume con-
trol dial. Turn the dial left or right to
adjust the volume to your liking.
For quick remote-control of volume
below the master setting—like mut-
ing—use the CAB-1 numeric keypad’s
volume control. Pressing AUX1 and
then 4 on the numeric keypad lowers
overall Railsounds output.

Choose from any between 1 and 99. To
make things easy, use a portion of your
72 ’s cab number, for example 72.
Turn the Command Base ON and
place the 72 on track. Slide the 72 ’s
reverse unit control switch to PRO-
GRAM (see the illustration), then
power up. Using CAB-1, press ENG,
the engine ID# (example: 72), then
press the SET button located under
CAB-1’s removable panel. Hear the
whistle blow (or see the headlight flash
if Railsounds is off); that’s the LCRU2
confirming the new ID#. Slide the
LCRU2 switch to FORWARD/RUN.

Your 726 Berkshire’s digital communication antenna
Y
our 72 locomotive’s wire handrails
are more than just model gra-
birons—they’re the LCRU2’s receiving
antenna for Command Base digital com-
munications. Please handle the 72 care-
fully to avoid handrail damage.
To ensure optimum reception, both
handrails are insulated from the 72 ’s
die-cast shell. If your 72 is experienc-
ing difficulty in receiving Base commu-
nications, check the handrail ends in
the cab and pilot for the presence of
insulating material. Ensure each stan-
chion is present and enjoys a proper fit.
Finally, prevent the handrails from
touching the steamchest/boiler front
between the last stanchion and the
pilot.The tubing on the handrail, near
the hinges at the boiler front, is factory-
installed to assure that the handrail
(antenna) remains insulated from the
metal. This gives the best reception for
the digital communications.
If the tubing is not desired, remove it
by lifting the handrail out of the cow-
catcher and sliding the tubing off.
Reinsert the handrail, making sure the
insulating bushing is in place.

Simply press the COUPLER R button on
your CAB-1 remote, and the tender cou-
pler opens, accompanied by the Rail-
sounds coupler release sound.

Using your Electrocoupler in the transformer-controlled environment
T
o use your tender’s Electrocoupler in
the transformer-controlled environ-
ment, you must first couple a piece of
rolling stock equipped with Lionel mag-
netic couplers directly behind your ten-
der. 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 the “trigger disc” on the rolling
stock’s coupler over the remote-control
track’s coil and press UNCOUPLE on the
track section’s controller. The magnetic
field pulls the disc downward, and the
coupler opens.
Your 72 tender’s Electrocou-
pler will NOT open manually
or by using a remote-control

Maintaining and servicing your 726 Berkshire
H
elp your Lionel 72 Berkshire lead a
long and productive life on your
railroad by maintaining it properly.
We recommend you purchase a
Lionel Lubrication and Maintenance
Kit (no. - 2927), available from your
Lionel dealer. Two basic rules to keep in
mind: never over-lubricate (a small
amount will do), and avoid getting
grease or oil on the 72 ’s wheels, con-
tact rollers, or your track.
You’ll know your 72 requires lubri-
cation when visual inspection reveals
dryness on the parts indicated in the
illustration. Remove accumulated dirt
and dust before lubricating, and always
lubricate any locomotive emerging
from prolonged storage. Also, lightly
lubricate the 72 ’s side rods after each
10 hours of operation.

Adding fluid to your 726 Berkshire’s smoke generator
Y
our 72 is equipped with a smoke
generator that produces safe, clean
white smoke during operation.
The smoke gener-
ator requires the
periodic addition of
Lionel smoke fluid
in order to function.
Pierce the tube end
with a pin, then add
four to eight drops
of fluid directly into
the 72 ’s stack.
Smoke production
will commence
momentarily, faster if you run your 72 at
speed. When smoke production wanes,
add more fluid (four to eight drops).
An idle 72 will not smoke. In
TrainMaster Command operations,
press AUX1 and 9 (press for a maximum
of 10 seconds) to
engage the smoke
generator at idle/in
neutral. Always keep
a small amount of
smoke fluid in the
72 ’s smoke genera-
tor; the generator’s
element can become
damaged if operat-
ed without fluid.
Smoke production is
greater at higher voltages and when the
72 is pulling a heavy load or long con-
sist.
Lubricating your 726 Berkshire’s die-cast motor casing
A
fter 80 hours of operating time or
after extended periods of storage,
you’ll need to lubricate the die-cast motor
casing. Remove the three screws that hold
the cab to the frame and lift off the cab.
Apply one drop of oil to the small hole in
the die-cast motor casting, just below the
field winding. Replace the cab and reinsert
the screws. After extended running, the
brushes may require replacement.
Sluggish or intermittent operation are
signs that brush replacement is due.
