APTA Definition for Light Rail

Light Rail is a mode of transit service (also calledstreetcar, tramway, or trolley) operating passengerrail cars singly (or in short, usually two-car or three-car,trains) on fixed rails in right-of-way that is oftenseparated from other traffic for part or much of theway. Light rail vehicles are typically driven electricallywith power being drawn from an overhead electric linevia a trolley or a pantograph; driven by an operator on board the vehicle; and may have either high platformloading or low level boarding using steps.
