Caltrain Modernization Program

Scheduled for implementation by 2020–2021, the Caltrain Modernization Program will electrify the corridor from San Francisco to San Jose—improving the performance, operating efficiency, capacity, safety, and reliability of Caltrain’s commuter rail service.

Harris is providing civil design services for the electrification work as a subcontractor to PGH Wong.

Core Elements

Harris’ scope of engineering work on the Caltrain electrification includes:

  • Preparing existing utility base mapping (wet and dry)
  • Identifying Joint Power Board (JPB) versus non-JPB utilities
  • Reviewing existing as-builts, record drawings, maps, and survey data
  • Resolving utility conflicts
  • Verifying any utility conflicts with proposed electrification improvements
  • Identifying High-Risk Facilities
  • Limiting utility transverse crossings (non-JPB utilities out of Caltrain’s ROW)
  • Designing the oil water separator for the ten new traction power facilities
  • Relocating all existing utilities around the new locations of the traction power sites
  • Utility encasement designs for existing pressurized utilities that are attached and exposed under the Caltrans and city-owned bridges
