The '''Caltrain Express''' ('''CTX''') (also known as the Baby Bullet) 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, California|San Jose]], and certain stations in between. New locomotives and rolling stock were purchased for dedicated express service, bypassing most stations; [[Quadruple-track railway|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 [[Track (rail transport)#Continuous welded rail|continuous-welded rail]]; a [[centralized traffic control]] system was added; and [[railroad switch|crossovers]] were added every few miles to allow single-tracking trains around disabled trains.

==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 [[ElectrificationCaltrain ofModernization CaltrainProgram|electrification of the line]].<ref name=98RRS />
 
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&nbsp;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>

===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 Stationstation|San Francisco 4th & King Street]] and [[San Jose Diridon Stationstation|San Jose Diridon]]: [[Millbrae station|Millbrae]], [[Hillsdale station (Caltrain)|Hillsdale]], [[Palo Alto station|Palo Alto]], and [[Downtown Mountain View station|Mountain View]].<ref name=SFC-040514 /> The ten trains consisted of three northbound and two southbound trains in the morning, and three southbound and two northbound trains in the afternoon; the two southbound morning trains and two northbound afternoon trains made additional stops at [[22nd Street station (Caltrain)|22nd Street]] to serve reverse commuters.<ref name=SFC-040514 /> Since these trains operated with far fewer stops, they took only 57 minutes to travel between San Francisco and San Jose, compared to 96 scheduled minutes for local trains making all stops,<ref name=SFC-040514 /> even though the maximum train speed remained at {{convert|79|mi/hour|km/hour}}.<ref name=SFC-040601>{{cite news |url=http://www.sfgate.com/bayarea/article/CALTRAIN-Baby-Bullet-to-premiere-Rail-2770861.php |title=CALTRAIN / 'Baby Bullet' to premiere / Rail travel between S.F, San Jose gets faster come Monday |author=Cabanatuan, Michael |date=8 June 2004 |newspaper=San Francisco Chronicle |accessdate=25 March 2017}}</ref><ref name=SFC-040608>{{cite news |url=http://www.sfgate.com/bayarea/article/BAY-AREA-Bully-for-Baby-Bullet-riders-say-2715103.php |title=BAY AREA / Bully for Baby Bullet, riders say / High praise, heavy loads for swift new commuter trains |author=Cabanatuan, Michael |date=8 June 2004 |newspaper=San Francisco Chronicle |accessdate=25 March 2017}}</ref><ref name=SFC-040403>{{cite news |url=http://www.sfgate.com/bayarea/article/BAY-AREA-Baby-Bullet-trains-shoot-for-June-2771698.php |title=BAY AREA / 'Baby Bullet' trains shoot for June rollout |author=Cabanatuan, Michael |date=3 April 2004 |newspaper=San Francisco Chronicle |accessdate=25 March 2017}}</ref>
