I'm awaiting arrival of my "DCC Ready" N Scale Bachmann Norfolk & Western #611 4-8-4 Class "J" Locomotive and am interested to know what decoders fit this unit. I realize that "DCC Ready" means that the motor is already isolated from the frame and not to expect drop-in installation. I've also installed DCC decoders in other N Scale Bachmann locomotives. Those units came with removable jumpers and had holes in the circuit boards to easily install the decoders. Does this unit require frame modification to house a decoder? Are there sound units available for this unit? Does anybody have a copy of the exploded parts list handy that will help me figure out what I'm getting into here? I run DCC exclusively ???on my layout and don't want to have a locomotive that sits idle (or in its box) most of the time because of potential overheating issues while running in DC mode on my layout. Thanx!
