Anyone know where there is an installation guide for the Bachmann Spectrum N scale 2-8-0. It's engine number 2506 and came in the 24121 item number steam set. It's one of the newer ones that says it is DCC ready. I can't find a socket, and would like to know which decoders would work best in this loco. The installation guides I have found seem to be for the older ones that have to be hard wired.
