The Caltrain Express Program (CTX) was implemented from 2002 to 2004 to establish the Baby Bullet express service, which shortened the transit time on the Caltrain commuter rail line between San Francisco and San Jose, and certain stations in between. New locomotives and rolling stock were purchased for dedicated express service, bypassing most stations; quad-track overtake sections were added in two locations along the Peninsula Corridor right-of-way to allow express trains to pass slower local trains that were making all stops; tracks were also upgraded with continuous-welded rail; a centralized traffic control system was added; and crossovers were added every few miles to allow single-tracking trains around disabled trains. Congresswoman Jackie Speier, then serving as a California State Senator, is credited with securing the funding for CTX and one of the new locomotives acquired for the project is named for her as a result. During commute hours, the Baby Bullet went up to 20 percent faster than driving south from San Francisco to San Jose. On September 21, 2024, with the completion of the Caltrain modernization project and the transition to electrified trains, the Baby Bullet was renamed as simply the Express service.
The Portal, also known as the Downtown Rail Extension (DTX), is a planned second phase of the Salesforce Transit Center. When complete, it will extend the Caltrain Peninsula Corridor commuter rail line from its current northern terminus at 4th and King via a 1.3-mile (2.1 km) tunnel. The new terminus will be near the Financial District and will provide intermodal connections to BART, Muni, Transbay AC Transit buses, and long-distance buses. In addition, the California High Speed Rail Authority (CHSRA) plans to use DTX and the Caltrain-owned Peninsula Corridor for service on the CHSRA San Francisco–San Jose segment. The Caltrain Modernization Program (CalMod), which included electrification of the line and acquisition of electrified rolling stock, was a prerequisite, since the former diesel locomotives were not suitable for use in a tunnel.
The Monterey County Rail Extension is a planned commuter rail extension that would bring Caltrain passenger service south of its existing Gilroy, California terminus to Salinas in Monterey County, using the existing Coast Line owned by Union Pacific (UPRR). Implementation of the rail extension will occur over three phases, starting from Salinas and moving north. When construction is complete, there will be four trains operated over the extended line per weekday: two northbound trains that depart from Salinas and travel to San Francisco in the morning, and two southbound trains that return to Salinas in the afternoon.
