how hard is it to consist locos. i just bought a EMD F7A-F7B units and will need to consist them when they arrive. ive read a little about it speed matching ect. my DCC of choice ia NCE system the consisting locos have digitrax decoders in them (not sure witch ) any hints or help would be much appreciated. i know ive got lots more reading ta do. But ive never done this. all new to me. but im looking forward to being able to run these on my new layout when i get it built.
OH ya there both KATO units. i only buy kato now. bachmann ticked me off and ive had great luck with kato so thats all i buy now. the others dont appeal to me as i like to use rapido couplers.
