Ok I have most of my track down on my new N scale layout but heres the problem : on a piece of flex track, the engine run fine, but when I place them on the main trackage with a 10 car train, I can only feel a light buzzing, and the light on the MRC power pack is very dim.. THIS IS NOT A LOCOMOTIVE PROBLEM> I'm assuming it is some thing electrical-related. In the general area, I have 4 switches. HELP ASAP!! Thanks, ------------------ TrainBoard.com MEMBER#204 N.A.R.A.
