Bachmann 94xx, One week old !! running light engine a little bit of a judder at low speed.?? It was run in correctly, i only have analogue, have any of you an answer??
I have replaced Heljan Brass Wheels on a Class 47 with 15mm steel wheels from Alan Gibson,Olham. The wheel centres are plastic so modification to the pick ups is required. No improvement in running. I think i should have just cleaned the Brass Wheels.
Do remember one side has to be insulated, the Heljan Brass wheels are a pain , you could use Brasso every day, may be not. Can you buy 15mm wheels for 2mm axles, not fine scale.
