GEC's Layout Progress

Gus: most electric railway systems used a wire or third rail for the power and the rails for the return. Some systems had 2 power wires because the local authorities didn't trust the conductivity of the tracks. Cincinatti street cars had 2 poles, like trolley buses, while the London Underground has an outside power rail and an inside power rail. Some systems had 2 wires in a tube under the street (Washington, DC). Double overhead wires had to be insulated just like HO turnouts.
