Transformer operations

Running your Lionel Commodore Vanderbilt with a Lionel transformer

Place your Commodore on Lionel or Lionel-compatible O gauge track.

• Note the pull of Magne-Traction® between your Commodore and the steeltrack. Magnetized wheels and axles increase pulling power (more than 25 carson straight and level track) and keep your Commodore on track while pass-ing swiftly through curves. Your Commodore will negotiate O-42 and largercurves. Note also the traction-enhancing tire installed on the center driversthat gives your Commodore extra driver-railhead grip. After extensive use, this tiremay require replacement. See your localauthorized Lionel Service Center forexpert tire-replacement service.

• With track power OFF, connect the loco-motive tether between the engine andtender. The six-pin tender plug connectswith the six-pin plug on the locomotive.Feed any excess tether into the engine cab. Connect the drawbar betweenlocomotive and tender.

Power up your Commodore with your transformer.

• Your Commodore is designed to operate on 8-18 volts alternating current.Virtually all Lionel and Lionel-compatible alternating-current transform-ers are suitable; we recommend the TrainMaster Command model rail-road control system.

• DO NOT POWER YOUR COMMODORE WITH DIRECT CURRENT (DC). Damage tosensitive electronic components may occur.

• When you first power up your track, the Commodore will wait between 3and 8 seconds as it “listens” for digital language from the TrainMasterCommand Base (available separately). When it’s determined that it’s on a con-ventional (nonCommand) railroad, the Commodore’s headlight will illumi-nate and Railsounds will fire up. At this point, the Commodore is in neutral.(This occurs when placing the Commodore on your railroad for the first time.Thereafter, it starts in forward after every three-second power interrupt.)

Note!

Move ‘em out!

• Get your Commodore moving. Press the DIR button on your CAB-1remote or Lionel transformer. This sequences the Liontech Commandreverse unit (LCRU2) to the next operating state.

• Adjust track voltage until your Commodore moves at your desired speed.

T o select a single operational state foryour Lionel Commodore (example:

forward only), you can deactivate theLCRU2’s sequencing function with thereverse unit control switch, locatedbeneath the cab overhang.

Get your locomotive moving in thedesired direction, then slow it down

without stopping. Set the reverse unitcontrol switch to PROGRAM/LOCK.The Commodore is now “locked” intoyour chosen direction.

When you no longer want single-direction operation, just slide thereverse unit control switch back toFORWARD/ RUN.

Your Commodore’s Railsounds system—the basics

L ionel Railsounds is the most realisticmodel railroad sound system in the

world. Your Commodore features theR a i l s o u n d sHudson digi-tal sound sys-tem for theultimate in real-ism.

Begin by in-stalling a 9-voltalkaline battery inthe tender. Thisensures full-fea-ture operation ofRailsounds. Thebattery compart-ment is locatedbe-neath the ten-der’s removablecoal hatch doors. Connect the 9-volt alkalinebattery to the lead.

Although Railsounds ispowered by track voltage,the battery is required for unin-terrupted operation. Useonly alkaline batteries.

When you first apply track power, theCommodore’s Railsounds system pro-duces sounds of the locomotive at rest. As

the Commo-dore moves,chuffing begins,increasing withthe locomo-tive’s speed.

To silence thesteam chuffing(whistle/bell areunaffected), slidethe Railsoundsswitch, locatedbeneath the coalhatch doors, tothe OFF positionbefore poweringup the locomotive.

The whistle is activated by using the lever orbutton on your transformer or CAB-1.

Discontinue locomotivepower for 10 seconds beforechanging the RailsoundsON/OFF switch position.

If Railsounds “drops out” dur-ing track power interrupts(direction change), replace thebattery.

Install a 9-volt alkaline battery in your Commodore’stender.

W ith Railsounds, you experiencethe sounds of real railroading like

never before. Simply put, it’s the mostsophisticated, authentic model railroadsound system in the world. Andremember—inside your Lionel 777Commodore are the sounds of theRailsounds Hudson digital sound sys-tem. No other electric train can offeryou authentic Hudson sounds. That’sthe power of Lionel.

• Variable chuff rate. Your Commodore’sspeed determines the steam chuff rate. • MultiWhistleTM. Different whistlesevery time—a Railsounds exclusive.• Authentic bell. Press BELL on yourCAB-1 or transformer to begin the

effect, again to discontinue. Even thefinal “hit” is muted like the real thing.• Reverse unit reset sound. Powerdown your track, wait for 3-5 seconds,and listen for the air-release sound—that’s the Commodore telling you itsLiontech Command reverse unit hasjust reset to forward operation. • Shutdown sequence. No othermodel railroad sound system shutsdown like Railsounds. Turn off trackpower, and after the air-release resetsound, you have two seconds to restartyour Commodore. If you’re done withoperations, Railsounds will commencewith an authentic Hudson shutdownsequence about two seconds after theair-release reset occurs.

Experiencing the range of your Commodore’s Railsounds system

Notes on Railsounds

• Use the volume control dial, locatedbeneath the tender’s coal hatch doors,to adjust sound output (see page 5).• Listen for incidental engine soundsduring Railsounds operation. They’reautomatic and, of course, authentic.• The 9-volt alkaline battery you installedensures continuous Hudson sounds, even

during short track-power interrupts.• Longer track-power interruptions (includ-ing locomotive derailments) cause Rail-sounds to shut down after about 7 seconds.• For even more authentic Railsoundseffects, operate your Commodore in theTrainMaster Command environment. Seepage 8 for details.

TrainMaster Command operations

Your Commodore in the TrainMaster Command environment

Lionel TrainMaster Command is the fun and sophisticated model railroad con-

trol system from Lionel. YourCommodore features the LiontechCommand reverse unit, which acts asboth a conventional reverse unit as well asthe key to unlocking many extra featureswhen you operate in Command mode.

TrainMaster Command gives you thepower to operate multiple Command-

equipped locomotives on the same track,at the same time. It’s the most fun youcan have with electric trains, and it’sincredibly easy too! Just follow thedirections below and you’ll be on yourway.

TO OPERATE IN COMMAND, YOU NEED A

COMMAND BASE AND A CAB-1 REMOTE.Find them both at your authorizedLionel retailer.

Place your Commodore 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 Lioneltransformer or the U on any of your installed PowerMasters.

• Once positioned on the track, increase track voltage to FULL (onPowerMaster, slide the CMD/CONV switch to CMD).

Address your Commodore 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 thentranslates your commands into digital code. That code is sentaround 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 trackpower—controls the actions of Command-equipped Lionels. Trackpower is simply like gasoline in the tank of your car—it gives youthe power to go places, but it doesn’t tell you where to go or howfast to get there.

• All Command-equipped Lionels come factory-programmed withan ID# of “1.” To change your Commodore’s ID#, see page 12.

Move ‘em out!

• Throttle up or press any command button on CAB-1. YourCommodore will respond to your every command. Read on. The funis just beginning!

Tuning your Commodore’s performance

MOMENTUMSimulate the labored performance of

a locomotive pulling a heavy load withmomentum. Press L, M, or H (locatedunder CAB-1’s removable panel) forlight, medium, or heavy momentum.The LCRU2 remembers the setting untilyou change it. For delayed response,use H. For quick response, choose L.

BOOSTING AND BRAKINGUse the BOOST and BRAKE com-

mand buttons for incremental controlof speed and a superior method for han-dling grades, stops-and-starts, andmore. Plus, using BRAKE in theCommand environment gives you abonus Railsounds effect—the ultrareal-istic sound of squealing brakes.

STALLMake your Commodore feel more

responsive by setting a “stall” voltage. Getyour locomotive moving, then press SET;the Commodore will stop. The headlightwill flash, indicating it’s in the SET mode.

Turn the throttle clockwise to get theengine moving, then decrease speed untilthe locomotive just stops. Then press SETagain; the LCRU2 remembers the stall set-ting until you change it. To clear stall, pressSET twice, holding it for one second eachtime.

HIGH VOLTAGE SETTINGPress SET, headlight will flash. Get your

locomotive moving to the maximumspeed you want it to run, press BOOST.Use this to keep your locomotive from acci-dentally being derailed at high speed.

SOUND QUALITYTo achieve your preferred Railsounds

master volume level, use the volumecontrol dial located beneath the tender’scoal hatch doors. Turn the dial left orright to adjust the volume to your liking.

For quick remote-control of volumebelow the master setting—like muting—use the CAB-1 numeric keypad’s volumecontrol. Pressing AUX1 and 4 on the key-pad lowers overall Railsounds output.

Maintaining your Commodore’s handrail antenna

Y our Commodore’s handrails aremore than just model grab irons—

they’re the LCRU2’s antenna for receiv-ing Command Base digital communica-tions. Please handle the Commodore care-fully to avoid handrail damage. To ensureoptimum reception, both handrails areinsulated from the die-cast shell. If your

Commodore experiences difficultyreceiving Base communications, checkthe handrail ends in the cab and pilotfor the presence of insulating material.Ensure each stanchion is present andenjoys a proper fit. Finally, prevent thehandrails from touching any part of thedie-cast locomotive cab.

Assigning your Commodore a new ID#

A s your Lionel Command-equippedfleet grows, you’ll want to give your

Commodore a more individualizedID#. Choose from any number between1 and 99. To make things easy, use a por-tion of your Commodore’s real-life cabnumber (5344), for example 53 or 44.

Turn the Command Base ON andplace the Commodore on track. Slidethe Commodore’s reverse unit controlswitch to PROGRAM (see the illustra-tion), then power up. Using CAB-1,press ENG, the engine ID# (example:53), then press the SET button locatedunder CAB-1’s removable panel. Hearthe whistle blow (or see the headlightflash if Railsounds is off); that’s theLCRU2 confirming the new ID#. Slidethe LCRU2 switch to FORWARD/RUN. Your Commodore is ready to runwith its all-new ID#.

H elp your Lionel Commodore lead along and productive life on your

railroad by maintaining it properly. We recommend you purchase a

Lionel Lubrication andMaintenance Kit (part no. 6-62927), availablefrom your Lionel dealer.Two basic rules to keep inmind: never over-lubri-cate (a small amount willdo), and avoid gettinggrease or oil on theCommodore’s wheels,contact rollers, or your

track. You’ll know your Commodorerequires lubrication when visual

inspection reveals dryness on theparts indicated in the illustra-

tion. Remove accumulateddirt and dust before lubri-cating, and always lubri-cate any locomotiveemerging from prolongedstorage. Also, lightly lubri-cate the Commodore’sside rods, drive rods, andlinkage after each 25hours of operation.

Adding fluid to your Commodore’s smoke generator

Y our Commodore is equipped witha smoke generator that produces

safe, clean white smoke during opera-tion.

The smoke generator requires theperiodic addition of Lionel smokefluid in order to function. Piercethe tube end with a pin, thenadd four to eight drops offluid directly into theCommodore’s stack.Smoke production willcommence momentarily, faster if yourun your Commodore at speed. Whensmoke production wanes, add more

fluid (four to eight drops). An idle Commodore will not smoke;

press AUX1 and 9 (press for a maxi-mum of 10 seconds) to

engage the smokegenerator at idle/inneutral. Always keep a

small amount of smokefluid in the Commodore’s

smoke generator; the genera-tor’s element can become damaged

if operated without fluid. Smoke pro-duction is greater at higher voltagesand when the Commodore is pulling aheavy load or long consist.
