The was a thread on this subject before. Contrary to a lot of answers, in Hornby speak DCC ready means they gave you a socket, quietly forgetting about the module and more importantly the mile of wire. I think a Hornby one will fit, I will check on my one later, to see how I did it. I sometimes buy a 6 pin Zimo wired one and rewire it to 8 pin as the decoder is smaller and there is a much shorter length of wire.
