Bus Tunnel

Seattle has a unique transit tunnel subway under downtown. It originally was designed for hybrid Trolley Buses. The buses run on overhead wires through the tunnel. Outside of the tunnel the switch to diesel power to run on the streets and highways. Meanwhile streets of Seattle have a mix of true trolley bus routes and traditional bus routes.

As built the tunnel had tracks for future light rail conversion. However the track was not adequate. The tunnel was closed to allow conversion. When it re-opened in 2009 the trolley bus wires were gone, light rail wire went up. Busses still use the tunnel with trains. However the busses used fuel cell technology so as not to cause hazards underground with diesel fuels.
