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.
Advanced Signal System Project - CBOSS PTC
The Communications Based Overlay Signal System (CBOSS) Positive Train Control (PTC) Project is an Advanced Signal System that will equip the corridor with federally-mandated safety technology and increase system capacity to help accommodate future increases in ridership demand. The Advanced Signal System will be interoperable with all other rail systems that access the Caltrain corridor, including commuter rail, freight rail and, in the future, high-speed rail.
