Positive Train Control Project

Project Overview

The Positive Train Control (PTC) Project is an advanced signal system that will equip the corridor with federally-mandated safety technology and increase system capacity with its future enhancement to help accommodate future increases in ridership demand. 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.

In December 2018, Caltrain met Statutory Requirements set by the FRA for submitting an Alternative Schedule Request. Caltrain commenced PTC Initial Revenue Service Demonstration (RSD) in September 2019 and achieved Interoperable with UPRR and ACE on Devember 9, 2019. The Caltrain PTC system is planned to be interoperable with Amtrak by April of 2020 and to receive PTC Safety Certification by 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.
