Burn, the one I got came DCC ready, to fit the decoder you have to lift the body off by cutting the glue line between the body and the chassis. I tried a bachmann 4 pin decoder and it jumped around the track. I then tried a standard hornby decoder, it was ok but not good at slow running. I then tried a hornby sapphire decoder, there was an improvement, and i'm sure if a mess with the CV's I could get it better. I hope this is a prompt for Noel to row in .
P.S. mine has rubber tractions tyres, and as its not all wheel pick it can stall over X crossings. I'm reluctant to take them off, anybody any thoughts on this?
