Beginning June 16, 2025, Tamien Station Electric Train service temporarily suspended. Info: caltrain.com/status.
Project Overview
The Positive Train Control (PTC) Project is an advanced signal system that equips the corridor with federally-mandated safety technology. PTC 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. The Caltrain PTC system was certified by the Federal Railroad Administration (FRA) in December 2020.
PTC is a key component of the Caltrain Modernization Program that will electrify and upgrade the performance, operating efficiency, capacity, safety and reliability of Caltrain’s commuter rail service, providing a modernized rail service that will help meet growing ridership demand between San Francisco and San Jose.
Goals & Benefits
PTC will monitor and, if necessary, control train movement in the event of human error. This will increase safety on the Caltrain corridor by preventing:
- Train-to-train collisions
- Overspeed derailments
- Movements through misaligned switches
- Incursions through work zones
Project Funding
The PTC Project is funded through a combination of local, regional, state, and federal sources.
