I am currently just getting started. The train set I had purchased is a Bachmann Santa Fe Flyer and so far its great. I have purchased more track for it and now I am thinking I might want to turn to DCC instead of just DC. The reason being is I am wanting to be able to purchase more engines and sets and I am not sure if I am going to be able to find the ones I want that run DC. So if anyone could answer my questions I'd appreciate this and there will be more questions to come! P.S. I am a Big Boy Fanatic!
