Hi Gary, Thanks for your reply To answer your questions, I don't have any other sound chipped loco, The loco ran fine with a non sound chip in, I have tried it on three tracks and a rolling road, I have ran a friends sound Scott and tornado with no trouble. I have altered the step's to 128, the fault come's on then at around 24. If the speed is jacked up sharply it occurs immediately. You say you have TTS sound chips, are they factory fitted, I have been told these decoders (as new from Hornby) are not available till July, this was sold to me as new!!! It's a query, New to the site, so just went for where I can ask a question, I think I have put this answer as another blog??

Hi all, New to DCC, using a Gaugemaster Prodigy express, fitted decoders to a number of Loco's. All working fine apart from a TTS A4 sound decoder, Sound works fine until the loco (Silver Link) starts to move, as I increase speed, when the speed reaches 8 on the cab, the loco stops, then starts again, then stops. The motor stops and starts regardless of sound on or off, idea it must be a CV that's wrong ( I have reset to 8, made no difference). Could it be Back EMF the problem
