Already many, many years I've been wondering about this, but have never dared to ask, but just to show my ignorance: Is is possible to have two trains moving independently on the same track if one is fed through the track and one gets it's juice through a catenary? And this, of course, without getting into fancy digital systems. With my very basic knowledge of wiring, I could think of both a reason why it would and a reason why it wouldn't work. So what's the deal? Is this the easy (apart from modeling the catenary) solution for running more than one train on the same bit of track or not?
