LIGHT RAIL

Lightweight passeger rail cars operating on fixed rails in right-of-way that is not separated from other traffic for much of the way. Light rail vehicles are driven electronically with power drawn from an overhead electric line (catenary). Modern-day term for a streetcar-type of transit operation. Traditionally this mode of transit consisted of mostly travel at grade in mixed traffic in the middle of the street using low platforms. The MTA Blue Line light rail system is actually a hybrid with many characteristics of so-called heavy rail. These include high level platforms and sophisticated centralized control systems. The Green Line has the exclusive use of its own rail right-of-way, and as such, meets the definition for both light and heavy rail.
