A cross-city connector: By adding an in-street light rail on or near Washington Street, you could travel east and west with frequent stops at popular destinations. You also could link with other routes, such as bus and/or train routes, to connect to other locations throughout the area.
Light rail is typically used in denser areas and the vehicles are designed for frequent stops along the route. Light rail can operate on existing roads among mixed traffic, eliminating the need for subway or elevated infrastructure.
