Motor Problems On Pre War Model Trains

January 9, 2006

One of the most frustrating motor problems encountered with pre-war model trains, is an “exploded” commutator. The problem is caused when the fiber washer holding the commutator assembly together fails because of old age. A sudden fragmentation of the three segments can result in motor failure. This can be spectacular when if it happens when the model trains are operating at full power.

Provided the commutator segments are in good condition, it is possible (in most cases) to have your commutator rebuilt using the original components.

You’ll probably need the services of experienced model train repairer who will require the armature and original commutator segments (if not too worn) in order to rebuild the commutator assembly.
