In some previous posts I asked questions about O and HO gauges to start setting up a train set for Christmas. I've done some research and have pretty much decided to start out with a MTH or K-Line GG1 passenger set, a number of nice ones which can be found on eBay. I'm going for period correct engine and cars. So, my question is what is a good starting transformer? My track will be a large figure 8 of Fastrack and I would like to be able to handle a good size O gauge set like a full Santa Fe Super Chief with cars eventually but not at the same time as the GG1 as well as just a few accessories. Where should I start with a transformer that isn't maxed out from the beginning?
Thanks.
