Document Description
Rail interlockings are a vital, fail-safe system in railway signaling that manage switches and signals to divert rail traffic between tracks to prevent collisions and to safely support maintenance activities. The A85 Interlocking is old and has been scheduled for replacement. It will eventually become unreliable and would result in disruption and/or delays to service. The Project would remove BART’s existing A85
Interlocking on the mainline tracks immediately northwest of Fremont BART Station and replace it with new components per current BART standards. The Project scope includes replacing components of the track structure, that is the running rails, guard rails, switch points, frogs, plates, ties, and top layer of ballast.
