CalMod: Caltrain Electrification


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 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. Sign up to receive the latest updates on Caltrain Electrification.

San Francisco Community Meeting

Please join Caltrain staff for a community meeting about Caltrain Electrification. Staff will provide information regarding the construction of a paralleling station in San Francisco.

In the coming months, crews will begin the construction of the paralleling station which will help distribute power to the new electric trains. The paralleling station will be located on the northeast corner of Mariposa Street and Pennsylvania Avenue. The meeting will provide an opportunity for residents to learn more about the project, including the scope and schedule of upcoming construction activities.
