I seem to have various speed problems with my TMCC engines on Legacy. I looked at the "speed step" threads but could not find anything which would help. Can you set something in Legacy for speed steps and how do I find what speed steps my engines have? When I turn up the volosity knob it takes forever then the engines starts up real fast then I can slow it down by turning knob down. I have tried the Momentum buttons but these don't seem to help. I have loaded the info from the generic chip and completed all steps in engine info section. Any ideasZZZZZZZZZ?

Steve,

What engine(s) are you running?

Do all of your engines behave this way?

Have you at set the Momentum on legacy? You could have hit the "H" button inadvertently. Try hitting hitting the "L" button.

BillP,

I am running the PW TMCC Texas Special F3, a Santa Fe Hudson w/TMCC. I am using a TPC as control source. When I start up I turn on the Legacy remote and puch TR1 (for my TPC) and L to get Command voltage; then ENG # then BUST. Power is on, eng responds with headlight and sound. But when I turn up Volocity wheel I have to turn so many times and when engine starts it is flying. My bar on the Legacy speed goes all the way to the end before engine responds. Have I programed the engine wrong?

Sorry guys...I ment BOOST not BUST....

In my livery I have various TMCC, Odyssey loco's in Lionel and K-Line, I find the problem you describe with my older locomotives pre Odyssey and with most K-Line. Try changing the sett up as a Cab 1 instead of TMCC. The generic chip defalts to TMCC.

I'm thinking that the track voltage when you start out is not at 18 volts or so and that when you are turning the dial both the speed steps and track voltage are increasing at the same time. You could see this with a clip on voltmeter, or for approximate indication, a lamp connected to the track.

To verify the operation of the locomotives and legacy, try using the legacy without the TPC and see how these engines behave in the TMCC mode. If they run better, then perhaps that is what is happenning.

Hope this helps.

To set the momentum on the legacy fef I have to push m and then turn the red dial either way to change the number. The other two buttons l and h only work in the old command base and handheld and l selects 32 speed steps on legacy engine, m sets 100 speed steps and no momentum and h sets 100 speed steps and momentum.
If you want fast response on your legacy engine, push m and turn the dial until you see a 1 on the screen and release the m button. I have pushed the l and h buttons in the legacy mode and nothing happens and not sure it will. You have 200 speed steps in the legacy engines and it is set at that.

Thanks for the responses...sometimes frustrating because you don't know if some little step was missed.

Phil - Will try to set as cab-1...I believe you ment to install engine info manually and not use generic module.

LIRR Steamer - will also check track voltage. I gather you mean the TPC is operating in conventional mode then. Lionel does not help setting priorities when you are operating more than one control unit. Do I set my TPC before addressing engine? Does this make a difference? The TPC instructions say to address TPC (TR#1 in this case), press L, to put TPC in command mode and light will blink fast to indicate voltage to track....all this happens. But your idea to check track voltage thru these steps I will do tonight.

winky - All my engines are non-Legacy. They are Lionel TMCC made in the mid to late 1990's. I truly believe my priorities in turning things on may be my problem.....I have not found in any manual what you should do first or last when you have Legacy, TPC and engine....any ideas?

Thanks again everyone.....mysteries are fun.....arn't they!

Texasspecial,

You can use the generic module to set the basics and then change them at any time of you can manualy set up a loco. I set up all my locos using the module and then modified them to obtain the best operating settings. If a TMCC loco has bad control (takes a long time to ramp up and then takes off) and the Legacy is set for TMCC with the momentum switch set on high then switch to CAB 1 setting and light momentum. Don't forget to release the train break in either Legacy or TMCC mode does not exist in Cab 1 mode. I have found that once the settings are correct all my loco's including the conventional loco through a TPC 400 or the new ZW operate smoother and better with Legacy.
On my Legacy system the L, M, and H momentum buttons work for all my comand loco's with the M being adjustable in the midrange from 3 to 6. Legacy allowes you to change the momentum on the fly which is a great improvement.
Checking track voltage is important I have installed either block signals or lighted logk ons' on all my blocks so that I can visually see that the power is on.
Good luck!

Check the brake slide. I did a dumb-dumb switching from Conventional back to commandand everything look normal and all the TPC lights worked but no movement. Then I saw I had slid the brake control all the way down.

Been there, done that too.

Hey Tex Special, I know on my TMCC I can set the "stall" speed. Maybe you can do the same with the Legacy.
