I purchased a Flying Scotsman. Lovely, but it buzzes instead of moving. When I start the HM2000 it moves about half a centimetre and if I slide the direction switch it'll move in the opposite direction about half a centimetre all the while buzzing. My Inter-City (40+ years old) is currently circumventing the track merrily. Current base is a bedroom carpet. Just a temporary measure out of curiosity to see if the Inter-City worked. Now it's the Scotsman's turn? Any thoughts?
