Hi, I've been perusing this forum and registered so that I could ask about the overhead. I don't model at present, due to time and other constraints, but I love the old traction railroads and really appreciate seeing the work done by those modelling them. In one of the earliest posts here, Interurban wrote, "That means ALL the wheels ground out on the track and the overhead supplies the power. Well that also means we have great running abilities." I don't understand how having a single contact point (pole or panny) on the 'hot' side and multiple contact points (the wheels) on the ground side could provide better running charateristics than multiple contact points on both the hot and ground (half the wheels for each polarity). It seems to be that the single contact point hot overhead would be much more likely to produce stalls than standard multiple point contact 2 rail operation. For the future traction layout I have in my head, I have always envisioned 2 rail DCC with strictly cosmetic overhead for the best running characteristics and most versatile operation. Can someone tell me what I am missing?
