At our club we are trying to run TMCC locos via the DCS system. We have the correct cables etc, we can add engines, but the engine starts at a fast speed. I have Barry's book but can't find the solution. What am I missing and not doing to get TMCC engines to start slower?

Dave,
If you're operating the TMCC engines under command control (TMCC) then the issue is with the engines themselves. They just have no speed control and also have a sharp acceleration curve under TMCC. There's nothing in DCS that can fix the problem.
I don't know a whole lot about TMCC engines, however, I seem to recall that one can set a "stall speed" that should retard their jackrabbit starts. Also, turning up the momentum on the engines (you can do that via the DCS Remote, if the TIU and command base are connected, or via the Cab-1) might help to slow them down, as well.
Lastly, you could try weighing them down with heavier cars.
If you're running them conventionally, try reducing the voltage by running them on variable channels at lower (5-8 volts) voltage. If that's still not slow enough, lower the voltage that goes into the variable channels.
Thanks Barry, will try your suggestions. And, hopefully, will see you at the fall York.
cheers

I ordered a Cruise Commander Module Control board. Be interesting to see if that makes the engine more useful. (This is for an Atlas RS-3 with Lionel TMCC already installed.)
