The biggest problem is the ease of destroying your Lego motor by supplying too
much current because the voltage will be too high.
The train motor does appear to have some type of thermal overload protection
in it but I couldn't see an easy way of keeping this when installing the
decoder [1] so ensuring you don't overload it is more important than in a non-
DCC system!
Other than that I don't see why you can't use an off the shelf system and try
and program the decoder to limit its top speed.
Of course the hardest thing to construct in my DCC project, is putting the DCC
encoder in the train motor, so using an off the shelf system doesn't exactly
make the project trivial!

metal that needs to be removed to isolate the motor from the rails.

| (...) Matt, how about setting the max. voltage of the decoder to 9V? I know some of the digitrax decoders (and the Lenz/Marklin) ones you can do this. James P (25 years ago, 21-Jan-00, to lugnet.trains)
