Hillsdale station (Caltrain)

Hillsdale station is one of three Caltrain stations in San Mateo, California. The station is next to the Bay Meadows neighborhood and close to the Hillsdale Shopping Center.



Bay Meadows station

Until it was closed on December 20, 2005, the Bay Meadows Racetrack was served by the now-removed Bay Meadows stop, less than a half-mile (800 m) north of Hillsdale. The Bay Meadows stop lacked a passenger shelter, and was just an opening in the chain link fencing where riders could access the grandstand parking lot. When Hillsdale was renovated, the platform was extended a few hundred feet to the north, eliminating the need for the separate station. Hillsdale is now the closest station to the former racetrack area.

The City of San Mateo applied for Measure A funds to help fund a grade separation project in 2013; the majority of the $180 million project is funded from Measure A ($74 M) and Proposition 1A ($84 million, California High Speed Rail). [2] The 25th Avenue Grade Separation Project elevated tracks in southern San Mateo, eliminating the at-grade crossing at 25th Avenue and adding grade-separated crossings at 28th and 31st Avenues, which previously had been interrupted by Peninsula Corridor tracks. [3] [4] Tracks will rise at the maximum allowable grade, starting from where they emerge south of the State Route 92 overcrossing, to minimize the depression of 25th Avenue to maintain vertical clearance for road vehicles under the new rail bridge. [3] The grade separation is also designed to accommodate a potential mid-line overtake required for Caltrain/HSR blended operations, which would expand the Peninsula Corridor right-of-way to up to four tracks. [3] PCJPB awarded an $82.9 million construction contract to the Shimmick/Disney Joint Venture in July 2017. [5]

As part of the grade separation project, Hillsdale station was relocated to the north. An initial design called for a station just north of 31st Avenue, with a transit center plaza and parking garage west of the tracks. [6] The final design has the station straddling 28th Avenue, closer to the transit-oriented development at Bay Meadows, approximately 2,000 ft (610 m) to the north. Preliminary renderings showed the new Hillsdale station with an island platform generally extending south from 28th, with parking provided east of the tracks. [2] A ceremonial groundbreaking for the grade separation project was held on September 26, 2017. [7] [8] Construction of the grade separations began in fall 2017 and originally was scheduled to complete in spring 2021. [9] The grade separation included five new rail bridges: one at Beresford Creek (completed by late 2018); [10] three to separate road traffic, installed in 2019 over 25th (July), 28th (September), and 31st (October); and a pedestrian underpass between 28th and 31st. Rail traffic was redirected over the bridges starting on May 28, 2020. [11]

The existing parking lot at Hillsdale was closed in 2018, and a temporary lot, accessible from 28th, 31st, and Delaware, will serve Hillsdale. After construction of the new Hillsdale station is complete, the temporary lot will be upgraded and serve as the new permanent lot. [12] In its final configuration, there will be two lots east of the tracks; vehicle access to both the north lot (between 25th and 28th) and south lot (between 28th and 31st) is available from 28th, and there is an additional access point from 25th for the north lot. [13] Passengers can connect to SamTrans buses along El Camino Real. The station was temporarily closed on May 16, 2020 and initially was scheduled to reopen in fall 2020. [14] The project, initially estimated to cost $180 million, had a cost overrun of $25.9 million due to delays. [15] The 28th Avenue grade separation opened on March 1, 2021; with its opening, the at-grade crossing at 25th was closed. [16] The station ultimately reopened at its new location on April 26, 2021. [17] Later that year, 25th Avenue reopened on August 2, [18] and 31st opened on August 27. [19]

The only below-grade Caltrain station, it is bracketed by two tunnels which take the line under the eastern slope of Potrero Hill. The station is reached only by stairways from 22nd Street and Iowa Street – there are no ramps or elevators between the platforms and street level – and is thus not accessible. The narrow stairways create bottlenecks, especially when northbound trains arrive.

The station opened by the Southern Pacific Railroad in 1866 as Fair Oaks and was renamed Atherton in 1912. Caltrain cut weekday service to the station in 2005 due to low ridership and a hold-out rule that prohibited two trains from being at the station simultaneously. Weekend service continued until December 2020.

Sunnyvale is a Caltrain station in Sunnyvale, California. The station is within walking distance of the historic downtown of Sunnyvale and the new Cityline Sunnyvale shopping center.

Dumbarton Rail Corridor

The Dumbarton Rail Corridor is a proposed transbay passenger rail line which would reuse the right-of-way that was initially constructed from 1907–1910 as the Dumbarton Cut-off. The Dumbarton Cut-off includes the first structure to span San Francisco Bay, the 1910 Dumbarton Rail Bridge, although the vintage Cut-off bridges would likely be replaced prior to activating new passenger service. Dumbarton Rail Corridor would provide service between Union City in the East Bay and Menlo Park on the Peninsula, with train service continuing to both San Francisco and San José along the existing Caltrain tracks. It has been in the planning stages since 1988, and would be the first above-ground transbay rail line since Key System electric trains stopped running on the lower deck of the Bay Bridge in 1958, and the first new transbay crossing of any kind since the completion of the Transbay Tube in 1974.

Caltrain Express

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) is a $1.9 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 Transbay Transit Center.

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.
