Mopath with constant vvelocity

Hello all…
I am trying to make a train composition of some cars to move on a mopath. The problem is that the train must have to follow the curve on a constant velocity, if not, the cars overlaps each other. But the velocity on mopath depends of the form of the curve is modeled on Maya.

what is the best form of doing this on panda?

thanks for all.

you have to rebuild the curve in maya before exporting it.
in maya, go to “surfaces->edit curves->rebuild curve” to arrange the cvs of the curve uniformly (be sure to give it enough “number of spans” in the rebuild curve tool options).
this should do the job.

thanks a lot man, it works fine.
