Peninsula Corridor Electrification Project

The Peninsula Corridor Electrification Project (PCEP) is a key component of the Caltrain Modernization program. The PCEP would electrify the Caltrain Corridor from San Francisco’s 4th and King Caltrain Station to approximately the Tamien Caltrain Station, convert diesel-hauled to Electric Multiple Unit (EMU) trains, and increase service up to six Caltrain trains per peak hour per direction. Operating speed will be up to 79mph, which is what it is today.

The primary purpose of the Project is to improve Caltrain system performance, reduce long-term environmental impact by reducing noise, improving regional air quality and reducing greenhouse gas emissions. An electrified Caltrain system would better address Peninsula commuters’ vision of  increased service and improved travel times in an environmentally friendly and reliable way. This also is expected to help accommodate increase system ridership through improved system operations. 

On September 6, 2016, Caltrain awarded contracts to Balfour Beatty to construct the electrification infrastructure and Stadler to manufacture high-performance electric trains. The electric trains are anticipated to be in service in 2022.

On January 8, 2015, the Caltrain Board of Directors approved and certified the PCEP Final Environmental Impact Report (FEIR) for the planned electrification of the Caltrain corridor between San Jose and San Francisco, a major milestone in the railroad’s efforts to improve its commuter rail service. For more information about the FEIR, click here.
