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 Trans-bay 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.
