Dear Alistair,
If you look at the pictures in post #10, in one of them, just alongside the socket where the decoder plugs in, is a long object made of a number of turns of wire on a straight round core. This is a choke - it is an 'inductor' and with the capacitors is part of the system to minimise radio/TV interference from the motor driving the loco. Unfortunately these componants can block/short-circuit the DCC signals and therefore need to be removed for most DCC systems (see what the instructions for your system say).
Why manufacturers cannot put them on the plug that goes into the DCC socket when a decoder is not fitted beats me - it would automatically remove them when a decoder is fitted. Or is that too simple?
Regards,
John Webb
