I've got one of the new TrackMaster Revolution engines (Talking Percy, came with a separate blue ice cream car). It's described here:
http://thomastrackmaster.wikia.com/wiki/...evolution)
It has a button on top (flush with percy's roof) and you simply press it to start the engine talking & moving. And press again to stop it.
It recently stopped working. I took it apart and tested the motor which works fine. Looks like the button is connected to a small computer chip which controls the sound&motor, etc. My guess is the chip or circuit died, and now engine doesn't work at all. I think the older engines just had a switch going directly to the motor with no fancy circuit inside.
But when it worked, it worked well on the latest TrackMaster tracks (the think grey plastic ones).
