I have an old one of these; the dates on the motor covers is 1994. I bought it several years ago but (for reasons of not having a railway to hand) never ran it until very recently. On first trying to run it, it would be deadly slow and very jerky, eventually grinding to a halt. Yesterday I cleaned the wheels and wheel contacts and now it runs pretty smoothly but painfully slow, even at 18.5 volts.
Any ideas as to what may be causing this slow running?
