I have had this engine from the beginning.
Last Xmas I took it apart to service it. Cleaned everything, lubed and reassembled.
This year I placed on track for first time today. It ran sluggishly for a while-then stopped.
Cycling the E unit produces nothing in forward or revers except a hum as if it was trying to go but couldn't.
The motor armature turns freely by hand--no binding all the way around.
Any thoughts on how to get this 65 year old engine running?

If it ran OK after you serviced it last year and before you packed it away, I would look for either a broken wire somewhere or excess lube that has gotten into where it should not be. Does the smoke in tender work? Just my thoughts...
Strip down and start again as below for starters.
Check brush springs for tension
Check brushes are not worn down
Check brush tubes for gunk
Clean armaure and slots
Check armature for continuity
Check reverse fingers are tensioned correctly
Clean reverse unit drum
Check all wiring for continuity from tender to engine
Lube as required everything that needs it
Make sure the reverse unit drum is clean and shiny, also clean the tender pick up wheels and the wipers on the axles. A dremel tool with a wire brush makes short work of cleaning the pick up the wheels and bronze wipers.
Progress report:
Disassembled as recommended. Found top finger assembly on E-unit broken and hanging. Have replacement part on hand.
Will report back when done.
Thanks for advice and encouragement.
