QUOTE All the Hornby DCC fitted locos I have dealings with have used a special four pin plug / socket which is non standard
In that case any mail order company who sends me a "Fitted" instead of a "Ready" will get it straight back. There are reasons why I choose to buy "Ready" locos:
1) I like to take advantage of "higher" end features such as ABC braking and RailCOM
2) I like to be able to add sound decoders easily
