Project Description

Peninsula Corridor Electrification Project, Santa Clara, San Mateo, San Francisco Counties, CA

The Peninsula Corridor Electrification Project (PCEP) is a key component of the Caltrain Modernization program. The northern portion of the PCEP would electrify the Caltrain Corridor over approximately a 50-mile section of the corridor from San Francisco’s Caltrain Station located at 4th and King Streets to approximately Tamien Caltrain Station in San Jose. The goal is to convert diesel-hauled to Electric Multiple Unit (EMU) trains and to increase service to six trains per peak hour per direction.

PARIKH is the geotechnical engineer-of-record (EOR) for the entire project. The project elements include the followings:

  • More than 3,000 overhead catenary system (OCS) poles,
  • More than 100 gantry structures,
  • Ten traction power facility (TPF) sites,
  • About 100 wayside facilities.

PARIKH Conducted more than 250 explorations along the entire corridor. Due to the access and limited right-of-way, we have engaged a 7-ton track-mounted Marl M5T Rhino rig on a Rail Rider SC30 (aka Low-Railer) to perform CPT from the tracks through the ballasts. More than 200 field soil resistivity tests were also conducted by the Wenner four-pin method per IEEE standard. All field work required close coordination with Caltrain, TransitAmerica Servics, Inc. (TASI), and the utility locators. PARIKH completed all field explorations with no incident.
