People in the San Francisco Bay Area rely on a complex multimodal transportation infrastructure consisting of roads, bridges, highways, rail, tunnels, airports, seaports, and bike and pedestrian paths. The development, maintenance, and operation of these different modes of transportation are overseen by various agencies, including the California Department of Transportation (Caltrans), the Association of Bay Area Governments, San Francisco Municipal Transportation Agency, and the Metropolitan Transportation Commission. These and other organizations collectively manage several interstate highways and state routes, two subway networks, two commuter rail agencies, eight trans-bay bridges, transbay ferry service, local bus service, three international airports, and an extensive network of roads, tunnels, and bike paths.
The Peninsula Commute, also known as the Southern Pacific Peninsula or just Peninsula, was the common name for commuter rail service between San Jose, California and San Francisco, California on the San Francisco Peninsula. This service ran as a private, for-profit enterprise beginning in 1863. Due to operating losses, the Southern Pacific Railroad (SP) petitioned to discontinue the service in 1977. Subsidies were provided through the California Department of Transportation (Caltrans) in 1980 to continue service, and it was renamed Caltrain.
The Oakland Coliseum station complex is located in the East Oakland area of Oakland, California, United States. The complex consists of two separate stations, Amtrak's Oakland Coliseum station, and Bay Area Rapid Transit (BART)'s Coliseum station, which are located approximately 600 feet (180 m) apart. The stations are connected to each other and to the Oakland Arena/Oakland Coliseum sports complex by an accessible pedestrian bridge.
Auburn station is an Amtrak station in Auburn, California. Located at the corner of Nevada Street and Fulweiler Street, it serves as the northern terminus of the Capitol Corridor line. The station is not staffed. The platform is next to a short spur track off Track 2 of Union Pacific Railroad's route over Donner Pass. Because of the geography of the city, the Union Pacific's mainline tracks are split, with Track 1 running through the eastern side of the city and Track 2 crossing the western side of the city. The California Zephyr bypasses the city on its route between Roseville and Colfax primarily via Track 1. Auburn became a stop on Amtrak's Capitol Corridor in January 1998.
Martinez station is an Amtrak passenger train station in Martinez, California, United States. Located at the west end of downtown Martinez, the station has one side platform and one island platform, which serve three of the four tracks of the Union Pacific Railroad Martinez Subdivision. It is served by the daily California Zephyr and Coast Starlight long-distance trains, five daily round trips of the San Joaquin corridor service, and fifteen daily round trips of the Capitol Corridor service. Martinez is also served by Amtrak Thruway buses plus County Connection, Tri-Delta Transit, and WestCAT local buses.
Hayward station is an Amtrak intercity train station in Hayward, California, United States. It is served by seven daily round trips of the Capitol Corridor route. The station has two side platforms serving the main track and a passing siding; most trains use the platform on the main track.
The Northern California megaregion, distinct from Northern California, is an urbanized region of California consisting of many large cities including San Jose, San Francisco, Sacramento, and Oakland. There are varying definitions of the megaregion, but it is generally seen as encompassing the San Francisco Bay Area, the Sacramento area, northern San Joaquin Valley, and the Monterey Bay Area.
The Caltrain Express (CTX) project was implemented from 2002 to 2004 and led to the establishment of the Baby Bullet express service, which shortened the transit time 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 is up to 20% faster than driving south from San Francisco to San Jose.
The Caltrain Modernization Program (CalMod), sometimes referred to as the Caltrain Electrification Project, is a $2.44 billion project that will add a positive train control (PTC) system and electrify the main line of the U.S. commuter railroad Caltrain, which serves cities in the San Francisco Peninsula and Silicon Valley, as well as transition from its current diesel-electric locomotive powered trains to electric multiple units (EMU). According to Caltrain, electrification of the tracks will allow it to improve service times via faster acceleration and shorter headways, reduce air pollution and noise, and facilitate a future railway tunnel into downtown San Francisco's Salesforce Transit Center, as diesel trains cannot serve underground stations.
The Downtown Rail Extension (DTX) is a planned second phase of the San Francisco Transbay Transit Center (TTC). 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 mi (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. Because DTX uses a long tunnel, current diesel locomotives are not suitable and the Caltrain Modernization Project (CalMod), which includes electrification of the line and acquisition of electrified rolling stock, is a prerequisite.
The California Zephyr is a passenger train operated by Amtrak between Chicago and the San Francisco Bay Area, via Omaha, Denver, Salt Lake City, and Reno. At 2,438 miles (3,924 km), it is Amtrak's longest daily route, and second-longest overall after the Texas Eagle's triweekly continuation from San Antonio to Los Angeles, with travel time between the termini taking approximately 511⁄2 hours. Amtrak claims the route as one of its most scenic, with views of the upper Colorado River valley in the Rocky Mountains, and the Sierra Nevada. The modern train is the second iteration of a train named California Zephyr; the original train was privately operated and ran on a different route through Nevada and California.
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.
