Why not light rail?
Light rail is a regional transit system, with relatively fast-moving, large cars designed to transport high numbers of people rapidly between suburban and urban areas. Streetcars are intended to go shorter distances in highly populated city neighborhoods. Streetcars are not intended to carry the same high volume of rush hour passengers as light or heavy rail, and therefore the cars are smaller. They can operate in mixed traffic, preserving the traffic patterns of neighborhood streets. They can stop more frequently and offer a more flexible service appropriate for city neighborhoods. Streetcar systems can be built more rapidly, more cost-efficiently, and with less disruption to businesses and communities from construction than light rail lines.
