As Brian said, it's not the motors, it's the RCX. You can run Technic motors off a
train controller, and you can vary the speed. But you need to do a bit more if
you're using the RCX.
We used that scheme when we controlled a train with an RCX.

There are plenty of ways to do what you want, this is just one of them. And, it is
exactly the same as what you want.
