I have my Dad's prewar American Flyer O Gauge 9900 Zephyr and just built a new layout with Ross track and Ross switches. It can't go through the switches and even the track is rough with the depth of the wheel flanges and the lack of space between the top of the track and the ties. It is the heavier cast aluminum Zephry. I don't have a loop of track that does not have at least one switch.
I guess I have two options, don't run it, just display it, which I don't want to do, or replace the motor.
Has anyone replace a motor so your prewar AF train so it can run on Ross track/switches, or any other low profile track? If so, any pictures or part numbers would be appreciated.
