I am about to build my first model train set in n scale, on a 4' x 8' plywood board. I was thinking of getting the Kato M1 and V2 and connecting them together, the reason being I want the incline in the tracks so I can build hills around it. I also like the idea of a bridge with tracks going under it Kato's site recommends 2 power packs with the M1 and V2 combo. The M1 comes with one power pack but how do I attach the second power pack and where? This is all one single track. If I use just the M1’s power pack alone will the tracks not be powered all the way through? Also, I have just learned about flex tracks but I have no clue about wiring, hooking it up, what parts to buy, etc. :dunno: Any suggestions? Thanks!
