Bart Traction Power Tender

Description:BART: Systemwide: Replace obsolete elements and subsystems of the traction power system to maintain and improve
reliability and safety. Additional components of this project for fiscal years 2006-2008 include:1. Purchase & install 9 Sub
Stations to replace Substations that are currently approaching the end of their useful life. 2. Install 4.5 Route Miles of 2
circuits of 34.5 kV Cables. 3. Purchase & install 20 more Negative Grounding Devices. 4. Purchase & install 150 more
Multi-Purpose Relays, which will be installed on DC Circuit Breakers that will be replaced in more than 5 years. These
relays have a number of features that will significantly reduce the severity & damage to the substations that have electrical
faults. This will significantly reduce the time for & the cost of repairs to the aging equipment & thus enable reliable train
service to be provided until all the Substations are replaced. 5. Replace / rehabilitate other parts as necessary on existing
substations to enable them to remain in reliable service until the Substations can be replaced.
