The '''Caltrain Express Program''' ('''CTX''')
==History==
In 1997, after plans to extend [[Caltrain]] to downtown [[San Francisco]] were put on hold, the Peninsula Corridor Joint Powers Board (PCJPB) started the ''Rapid Rail Study'', which was published as a draft in October 1998.<ref name=98RRS>{{cite report |url=http://bayrailalliance.org/files/library/Caltrain_RRP_draft.pdf |title=Draft Caltrain Rapid Rail Study |date=1 October 1998 |publisher=Peninsula Corridor Joint Powers Board |accessdate=29 March 2017 |archive-url=https://web.archive.org/web/20110807145542/http://bayrailalliance.org/files/library/Caltrain_RRP_draft.pdf |archive-date=7 August 2011 |url-status=live }}</ref> The 1998 ''Rapid Rail Study'' prioritized planned capital improvements to implement the 1997 ''Caltrain 20-Year Strategic Plan'', which sought to improve service and increase ridership, which was assumed to correspond directly to improved service (through decreased transit times and increased train frequencies). The highest-priority projects were intended to rehabilitate the line to "reverse decades of deferred maintenance" and enhance the line by adding [[passing loop|overtake tracks]] to implement express service.<ref name=98RRS /><ref name=99RRSIP /> After rehabilitation and enhancement, the ''Rapid Rail Study'' called for [[
Proposed rehabilitation work included rebuilding tracks and grade crossings to enable Caltrain to raise the systemwide speed limit to {{convert|79|to|90|mph|abbr=on}} and replacing bridges, culverts, and signals.<ref name=98RRS /> The initial enhancement projects included adding third overtake tracks in Burlingame (between the stations at Millbrae and San Mateo, for northbound trains) and San Mateo (between 9th Avenue and Hillsdale, for southbound trains) to allow express trains to pass slower all-stop local trains, and adding a third [[pocket track|turnback track]] in Palo Alto to allow more frequent short-line service.<ref name=98RRS /> In 1999, PCJPB published an implementation plan for the ''Rapid Rail Study'' which called for a $280 million investment from the three counties served by Caltrain.<ref name=99RRSIP>{{cite report |url=http://bayrailalliance.org/files/library/Caltrain_RRP_implementation_plan.pdf |title=Caltrain Rapid Rail Study Implementation Plan |date=1999 |publisher=Peninsula Corridor Joint Powers Board |accessdate=29 March 2017 |archive-url=https://web.archive.org/web/20110807145429/http://bayrailalliance.org/files/library/Caltrain_RRP_implementation_plan.pdf |archive-date=7 August 2011 |url-status=live }}</ref>

In 2017, the ''Rail and the California Economy'' report noted that Baby Bullet trains operated at 95% on-time performance (making stops within ten minutes of scheduled times) and, at around 60 minutes from San Francisco to San Jose, was faster than driving south on U.S. 101 during key commute hours. Driving times during peak afternoon commute hours could reach 75 minutes or more.<ref>{{cite report |url=http://www.dot.ca.gov/research/planning/docs/Rail_CAEconomy_Book_Report.pdf |title=Rail and the California Economy |author=Institute of Transportation Studies, University of California, Berkeley |date=2017 |publisher=California Department of Transportation |accessdate=31 August 2017 |archive-url=https://web.archive.org/web/20170831140440/http://www.dot.ca.gov/research/planning/docs/Rail_CAEconomy_Book_Report.pdf |archive-date=31 August 2017 |url-status=live}}</ref>
On September 21, 2024, with the completion of the [[Caltrain Modernization Program|Caltrain electrification project]], the Baby Bullet was renamed as simply the "Express" service.<ref name=":0" />

===Station rebuilds===
During the CTX project, Caltrain rebuilt the [[Bayshore station (Caltrain)|Bayshore station]], relocating it slightly south of the prior ___location to accommodate the north quad track overtake section ending just south of Tunnel #4. This moved nearly all of the Bayshore station out of the City and County of [[San Francisco, California|San Francisco]] and broke a planned intermodal connection to the [[Third Street Light Rail Project]], the first expansion phase of the [[Muni Metro]] light rail system, which was building tracks down [[Third Street (San Francisco)|Third Street]]. The new [[T Third Street]] line, which opened in 2007, terminates at [[Sunnydale Station]] as Muni Metro has never built any tracks in [[San Mateo County]], and a planned {{convert|0.5|mi|adj=on}} loop extension to Bayshore was studied in 2012.<ref>{{cite report |url=http://www.sfcta.org/sites/default/files/content/Planning/Bayshore/Bayshore_final_report.pdf |title=Bayshore Intermodal Station Access Study |author=<!--Staff writer(s); no by-line.--> |date=March 2012 |publisher=San Francisco County Transportation Authority |accessdate=26 March 2017}}</ref><ref>{{cite news |url=http://www.sfgate.com/bayarea/article/Bayshore-Station-envisioned-as-vibrant-transit-hub-3451733.php |title=Bayshore Station envisioned as vibrant transit hub |author=Wildermuth, John |date=28 April 2014 |newspaper=San Francisco Chronicle |accessdate=26 March 2017}}</ref> A small rail bridge south of Bayshore was built over a creek as part of CTX.<ref name=Cal-0211 />

===Stops and scheduling===
Baby Bullet service launched in June 2004 with ten trains per weekday, which made only four intermediate stops between [[San Francisco 4th and King Street

Caltrain service on weekends north of Bayshore was suspended and replaced by a bus bridge from October 2018 to March 2019 in order to accommodate tunnel notching work for the Peninsula Corridor Electrification Project. Weekend Baby Bullet trains originated and terminated at Bayshore, and a bus bridge made stops at both stations in San Francisco.<ref name=TT181006>{{cite web |url=http://www.caltrain.com/Assets/_Marketing/pdf/Caltrain+Weekend+Timetable+with+Bus+Bridge.pdf |title=Weekend Timetable with Bus Bridge |date=October 3, 2018 |publisher=Peninsula Corridor Joint Powers Board |accessdate=3 October 2018}}</ref>
In response to the [[COVID-19 pandemic]] and loss of passenger traffic, Caltrain discontinued all weekday Baby Bullet service from Monday, March 30, 2020, to August 27, 2021, and all weekend Baby Bullet service indefinitely, starting December 12, 2020.<ref>{{cite press release |url=https://www.caltrain.com/about/MediaRelations/news/Caltrain_to_Implement_Additional_Weekday_Service_Reductions.html |title=Caltrain to Implement Additional Weekday Service Reductions |date=March 26, 2020 |publisher=Peninsula Corridor Joint Powers Board |accessdate=28 December 2020}}</ref> Weekday Baby Bullet service
Effective September 21, 2024 with the transition to [[Caltrain Modernization Program|full electric service]] between San Francisco and San Jose, Baby Bullet service was discontinued and rebranded as the "Express" service. 14 Express trains run each weekday, 3 per direction during peak morning commute hours and 4 per direction during peak afternoon commute hours. <ref name=":0" /> Express trains make nine stops between San Francisco 4th & King and San Jose Diridon: 22nd Street, South San Francisco, Millbrae, San Mateo, Hillsdale, Redwood City, Palo Alto, Mountain View, and Sunnyvale, with a scheduled journey time of 59 minutes. Select Express trains provide timed cross-platform transfers at San Jose Diridon to and from South County Connector diesel trains for continuing service to Gilroy.
