I am still having problems with this loco. I completely stripped the motor, cleaned and lubricated it, etc, but it still won't start smoothly. I turn the controller up and it suddenly starts off but will then run slowly if I turn the controller down. What causes this? Maybe it is just too worn out. Maybe I will try a CD conversion on it.
Back in the 70s I bought a brand new one and it was dead smooth at all speeds and made a just a light rustling sound as it ran.
