I'll take a stab anyway.bbqboy wrote: Could you guys tell me the standard definitions of streetcars, light rail, heavy rail, and commuter rail?...or at least as far as their usage on this here little forum? Thanks.
Light rail is typically characterized by its stop-and-go nature. It is the multiple stop, urban corridor rail system. It can operate on normal tracks, but it is usually a sleeker, smaller car and runs on electricity. Think sliding doors, easy entry, standing room, etc.
Commuter rail is typically run on conventional track with conventional passenger train type configurations. Its purpose is usually to connect the center of a suburban community with a transit hub in the city. Thus, stops are limited. Commuter rail is typically used in a park and ride fashion, or when using transit in the source community to reach the train for the trip to the city.
Street cars are a form of pseudo light rail, though light rail sometimes connotes use of off-the-road infrastructure while streetcars operate on existing streets. Streetcars are usually smaller but still use tracks and electric engines.
If that is off base, everyone can have at it.
