Take a behind-the-scenes look inside our new electric trains (see full GIF). From flooring, ceiling lighting, overhead storage, and new stair railings, the interior components are coming together. With the first seven-car trainset now assembled and more car shells on their way, it's time to get excited for your modernized commute!

Caltrain tracks early in the morning.

The kilometer-long test track construction in Salt Lake City continues to progress with track, power poles, and electrical transformers installed. Next the overhead wires will be in place and connected to transformers for the running of the first seven-car trainset in April. This will mark the beginning of a two-month period of testing at our train manufacturing facility in Salt Lake City, Utah. Click the link below to learn more about our new electric trains!

To accommodate the new electric trains, construction crews are continuing work in the four San Francisco tunnels. As of February 22, crews have installed the drop tubes, termination structure, and three of the four required wires.

Crews also continued installation of poles from Menlo Park to San Jose and performed work on six traction power facilities in San Jose, Redwood City, Sunnyvale, South San Francisco, and San Mateo.

What Is CalMod?

The Caltrain Modernization Program (CalMod) includes electrification and other projects that will upgrade the performance, efficiency, capacity, safety and reliability of Caltrain's service. The current electrification project will electrify the corridor from San Francisco to San Jose and replace 75 percent of Caltrain's diesel service with high-performance electric trains, reducing air pollution and providing better service to more riders.
