I'll give everything a good clean but I fear it might be a split gear.

I had a Jinty that was going something similar

After a lot of time investigating it turned out to be the frame around the motor had de-bonded and was moving about. Super glued back together and problem sorted

I have given the commutator a good clean, it didn't look too dirty.

I spotted something else that may have caused the problem, the plastic covering on the wire that runs along the top of the chassis to the tv suppression thingy had shrunk and the wire was touching the top of the copper brush clip. I assumed that wasn't good and added some insulating tape.

The loco is now running well again, touch wood  :D

 :thankyousign:

For all the help.

Sounds like you cracked it. Great news. Time to play trains again. Yippee  :claphappy:
Size matters - especially if you don't have a lot of space - and N gauge is the answer!

Famous last words! My pannier is back to its old tricks, so much for my theory.

My older Poole Farish locos are gradually failing which is sad because I really like them very much. I was hoping they'd be like miniature Hornby Dublo locos and last forever.

I've had a couple of Poole chassis that run slowly and draw a large current. The current remains high even the gears demeshed. This was caused by incorrect end float on the armature caused by tight bearings and top housing, they were the original parts. Both are still available.

Just a thought, is the commutator getting dirty again. Some of the brushes seem very soft and the commutator needs cleaning quite often.

Once I had a commutator that was so dirty it took a couple of minutes before it would start to move. That'll teach me!

The commutator is clean as are the commutator slots, I'm going to check the bearings next. Thank you for the suggestions.

I think I have found out what the problem is, having another look under my magnifying lamp, I found a split in the gear collar. It looks as though the actual gear is ok but that may be split as well. I assume that the gear is loose on the axle which is causing the spinning.

Next time I'm in the UK I will add the loco to the pile to be sent to B R Lines.

I thought back at the start of this thread we established the symptoms are the wheels spinning on the track and the loco not moving?  A gear loose on the axle wouldn't cause that, instead you'd just get the motor running with the wheels not turning at all.
