Just tested the motors applying 5VDC. The Whistle Steam side motor worked , the stack side motor is locked up solid; won't budge even by g-e-n-t-l-y nudging the impeller.
Order already placed with Lionel Parts. Ordered 4 traction tires, 3 resistors, 2 motors, 1 gasket, 1 wick and a Partridge in a Pear Tree!
The preformed wick "block" NA; had to go with rope wick.
