Electric Trains

Caltrain is purchasing new high-performance electric trains to replace the current diesel locomotive trains as part of the Peninsula Corridor Electrification Project. The electric trains will stop and start faster than diesel trains which means Caltrain could increase capacity with a more user-friendly, efficient schedule that will provide consistent, attractive service with more frequent stops without sacrificing speed.

Caltrain’s new electric trains are a key component of the Caltrain Modernization (CalMod) program that will enhance the speed, capacity, safety, and comfort of Caltrain’s commuter rail service.

New Passenger Cars

A typical passenger car layout will have two main levels with between 85 and 100 seats per car. There will be some flip seats, in addition to the regular fixed seats. Most seats will face one direction and if there are any seats facing each other, there will be a table in the middle. There will be one bathroom per train.

Rider engagement is a key element helping to shape the design of Caltrain’s new electric trains. Based on a review of the feedback received, the stacking option, which maximizes onboard capacity will be the onboard bike storage design for the new electric trains.

Rendering of the stacking bike design

During August through September, the Caltrain outreach team worked to receive feedback on the electric train onboard bicycle storage design. Over this time, Caltrain collected feedback through various feedback mechanisms used to make the final determination. Input was received through an online poll; discussions with local bike advocacy groups; station outreach where riders could try out the bike car options; comments though the website; social and earned media; and emails, phone calls, and in-person-engagements.

The poll, which ran from August 8 to September 1, found that two-thirds of respondents (66.2 percent) preferred the convenience of the hybrid, wheel-holder option. Written comments from some members of the public expressed concern that the hybrid option would not be able to accommodate all bikes; would limit capacity, causing more cyclist bumps from trains; and would not be accessible to those unable to lift their bike into the wheel holders. The Caltrain Bicycle Advisory Committee and the bicycle coalitions in San Francisco and Silicon Valley supported the stacking option due to its ability to maximize onboard bike storage.

New Bike Cars

There will be two dedicated bike cars per train that will be well marked. Each bike car will have a lower, mid, and upper level, with bike storage on the lower level. Security cameras will be posted in each bike car to enhance security.

Note: Caltrain recently adopted a Bike Parking Management Plan to improve bike parking at stations. For more information about the plan, go here.

Replacing old diesel trains with new electric trains will reduce GHG and improve air quality


Initially, Caltrain will replace approximately 75 percent of the diesel fleet with new electric trains called Electric Multiple Units (EMUs), which would operate between San Francisco and San Jose. Full replacement of the fleet with EMUs would occur at a future time when funding is identified and the remaining diesel trains reach the end of their service life.
