Happy Holiday! My son just received a gift "Lionel Great Northern Glacier Route Freight" starter set and we would like to expand on it. First, we would like to add some additional Fastrack tracks, that would involve 4 switches. I would prefer remote switches. Are remote switches available in the Fastrack lineup yet? Second, since the trainset came only with a 40 watt transformer, would I need to step up the transformer because of the increase number of tracks and remote switches? Thanks!
