Overview
Traction Power Facility 1 is a substation operated by Caltrain in the United States, providing traction power for rail operations with voltage levels of 115 kV and 25 kV.
Traction Power Facility 1 is a substation located in the United States, operated by Caltrain to supply traction power for rail operations. The facility is operational and serves as a critical component of the regional rail infrastructure, converting high-voltage transmission power to levels suitable for train operations. The substation operates at voltage levels of 115,000 volts and 25,000 volts, indicating its role in stepping down power from the transmission grid to the traction network. As part of the Caltrain system, it supports commuter rail services in the San Francisco Bay Area, a region with high population density and significant transportation demands. The facility is subject to NERC reliability standards and FERC regulations for grid interconnection. This substation plays a vital role in ensuring reliable power supply for electrified rail services, contributing to reduced emissions compared to diesel operations. Its location in an urban corridor underscores its importance for sustainable public transportation and grid stability in a major metropolitan area.
Environmental context
The substation is located in an urban environment near San Francisco, where electrified rail reduces local air pollution and greenhouse gas emissions compared to diesel alternatives. The facility's voltage levels indicate integration with the regional transmission grid, which may draw from diverse energy sources including renewables. Its operation supports modal shift from road to rail, aligning with climate goals.
