I purchased an MTH BUDD car set w/ protosound. Item #: 30-2144-1. When I put the engine on the track, it does not sit in neutral, it moves forward. When I power down the transformer and power up, it still moves forward, it does not go into neutral or reverse. Any help?

Reset the system. You can select that action. One of my MTH PS-2 3 rail engines is set to only run forward with any throttle movement.
how do i do that? There is a switch underneath - do I move that one was or the other?
It may be locked in forward. To unlock, power the loco up to 8 volts and press and hold the horn button while turning the throttle off. Release the horn button. After 3 seconds, a single bell should be heard, then immediately power up the throttle and test. A reset 18 is also recommended. If that doesn’t work, the transistor or relay on the power board may be shorted.
That doesn't work because while 8 at volts it seems to remain in place, once I increase the power per your suggestion, it just takes off forward like a rocket. Any other ideas?
what is reset 18?
Try a low enough voltage to get it moving, then try the unlock procedure. If that doesn’t work, it may be a power board problem.
First this is suppose to be a PS-1 engine. Does it start up with sounds when moving or just start moving? It may not be PS-1 any more, or maybe someone swapped in a non PS-1 engine and it has a DCRU. There would be a switch for locking the DCRU in a direction. Move switch to other position and it may resolve this. Until this is opened and inspected you really do not know what you have. Additionally, if a pinched motor wire the engine can also move on power up. G
