Document Description
The San Francisco Bay Area Rapid Transit District (BART) is an electricity powered commuter transit line. Electrification is provided by "traction power" substations located along the transit line right-of-way. BART proposes improvements to one of its existing gap breaker stations, referred herein as "MCG". MCG is located below-ground in the lower gallery of the Transbay Tube Tunnel in San Francisco County. The gap breaker station isolates appropriate electrified third rail sections for maintenance and repair purposes and de-energizes third rail sections during emergencies for the M-Line. Please see Attachment A for additional information.
