Caltrain Modernization

Program Overview

The Caltrain Modernization Program (CalMod) includes electrification and other projects that will upgrade the performance, efficiency, capacity, safety and reliability of Caltrain’s service. Electrification provides the foundation that future CalMod improvements are based on, including full conversion to an electric fleet, platform and station improvements, the extension of service to Downtown San Francisco, and other projects that allow Caltrain to grow and evolve with the Bay Area.

Caltrain Electrification is a key component of the CalMod Program. The current project will electrify the corridor from San Francisco to San Jose and will replace 75% of Caltrain’s diesel service with electric--providing cleaner, greener, and better service to the Caltrain community.
