Grahame Ainge

Many thanks to everyone for the helpful replies. I did wonder if cleanliness of wheels might be the cause and will now give them an extra clean. Loco at present in works undergoing name and number change etc I am still only dabbling with DCC and this is my third sound loco. May not convert 100% due to expense of converting a large collection. Will contact my nearest model shop if I need to. They are excellent and I'm sure will be able to disable DC on the decoder. Will report back when problem solved.

I have a Hornby factory fitted DCC Kidwelly Castle R2897XS and although it works well most of the time, sometimes when the controller knob is turned (F1activated) the loco shoots off down the track (Bachmann E-Z Command Control). Any ideas please how to solve the problem since it can do a lot of damage when it unexpectantly happens? As you may guess I'm pretty new to DCC. Many thanks, Grahame
