Hi Pete,
Thanks for the advice I did suspect that was the case I do have a H&M so will make sure I don't use half wave. I do plan switching to DCC so that is a result although I am getting a running issue in 1 direction all good but in the other it coughs and splutters and doesn't want to go until I give it plenty of volts ie: no slow running only fast could that be the decoder? I have checked every other possible cause and started to suspect it's causing the issue, bit strange it,s only in one direction.
Thanks
Andrew.
