Why High-Performance 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.

New Bike Cars

There will be two dedicated bike cars per train that will be well marked from the outside. Each bike car will have two levels, with bike storage on the lower level. The exact bike layout will be discussed in Spring/Summer 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.

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. Explore the timeline below to learn more about the schedule.
