Caltrain plans to purchase new high-performance electric trains to replace the current diesel locomotive trains as part of the Peninsula Corridor Electrification Project. The electric trains would stop and start faster than diesel trains which means Caltrain could increase capacity with a more user-friendly, efficient schedule that would 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.

Project status: This project is contingent on federal funding. For more information about the project status click here.

Explore Potential New Caltrain Electric Trains

If federal funding is secured, Caltrain plans to purchase new high-performance electric trains to replace the current diesel locomotive trains. This tour will highlight some of the exciting new features of the high-performance electric trains. Keep coming back to the website for updated information and ways to provide your feedback.


The new electric Caltrain train would be state-of-the art vehicles with many enhancements and amenities over the current diesel fleet.

New Passenger Cars

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

New Bike Cars

There would be two dedicated bike cars per train that will be well marked from the outside. Each bike car would have two levels, with bike storage on the lower level. The exact bike layout will be discussed in Spring 2017. Please visit again to see the latest developments.

Note: Caltrain is in the middle of developing a bike parking management plan that will explore opportunities for improving bike parking at stations. For more information about the plan and to weigh-in, go here.

Exterior Design

Vote on the New Train Exterior Design

Voting closed Midnight on Friday May 19th. Thank you for voting!

As we move closer to finalizing various design aspects of the new electric trains your input will not only help shape how we deliver a more comfortable ride and more efficient service – but what the trains look like as well.

Rider feedback is one of several important factors we will consider in choosing the final exterior design. Spread the word, Share this poll with your network! Check back soon, as we will be posting updates on the poll outcome next week. Want to see how the designs would look on a six-car train? Click here.

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


Initially, Caltrain plans 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. Explore the timeline below to learn more about the schedule.
