Reply to "1991 Lionel Warbonnet TMCC Problem"

It's pretty easy to test the motors independently by just wiring the field coil to one brush, and the other brush to the center rail.  The other end of the field is frame ground, so that should spin the motors.  If that works, you need a little repair on the AC commander, likely the Q4008L4 triacs have been toasted.  They're cheap and readily available, not a difficult repair.
