Also by powering up you will find if the motor / electrics is the problem.

I have taken out each of the drive wheel sets from the the bogies and given the wheels a twist if I feel movement check the plastic drive gear with a magnifying glass and you may see a hairline crack, discard said wheel set and replace the the drive gear , do not chuck out the wheel set, gears are available on eBay and are a easy fix. I have noticed that locos who have had a constant overloaded train load can put a large strain on the transmission gear , if a large amount of cars are required to be moved do like the real guys and double up on the locos to pull it. Regards John and I hope this helps.

I had similar problem with Digitrax decoder. Problem found in CV29 (Same CV on Broadway Limited). By default it’s set to 14-bit control. Change it to 28-bit. Leon.

It sounds mechanical to me. Maybe just a good cleaning and lubrication of the gears, etc is required.

I ran the loco in reverse at top speed for a few seconds. I then turned the loco over and discovered a very fine clear string bunched on one gear.Very carefully I pulled out the fiber ,now the loco runs fine.

Clogged with old grease and need to be run to loosen up
