Program Overview

PROGRAM OVERVIEW

Caltrain electrification is a key component of the Caltrain Modernization (CalMod) Program and will electrify the corridor from San Francisco’s 4th and King Caltrain Station to the Tamien Caltrain Station. Electrification improvements include converting diesel-hauled trains to Electric Multiple Unit (EMU) trains, increase service to six trains per peak hour per direction, and maintain operating speed up to 79 mph.

The primary purpose of Caltrain electrification is to improve Caltrain system performance and curtail long-term environmental impacts by reducing noise, improving regional air quality, and lowering greenhouse gas emissions. Electrification improvements will better address Peninsula commuters’ vision of increased service and improved travel times in an environmentally friendly and reliable way. These service improvements are also expected to help accommodate increased system ridership through improved system operations.
