In 1993, five transit agencies (AC Transit, BART, SamTrans, Union City Transit, and VTA) formed a consortium to fund the service. A third route, DB2, was introduced in October 1998. It operated between Union City station and the East Palo Alto area.{{cite news |url=https://www.newspapers.com/article/oakland-tribune/145883619/ |title=Dumbarton Express offers free bus rides |first=Ronna |last=Abramson |newspaper=Oakland Tribune |date=January 9, 1999 |page=13 |via=Newspapers.com}} The route saw low ridership and was discontinued on June 30, 2001.{{cite news |archive-url=https://web.archive.org/web/20041030134449/https://www.almanacnews.com/morgue/2001/2001_05_23.bus.html |archive-date=October 30, 2004 |url=https://www.almanacnews.com/morgue/2001/2001_05_23.bus.html |date=May 23, 2001 |title=Dumbarton bus line canceled |newspaper=The Almanac}}{{cite web |archive-url=https://web.archive.org/web/20020214174538/http://www.actransit.org/news/articledetail.wu?articleid=10032469 |archive-date=February 14, 2002 |url=http://www.actransit.org/news/articledetail.wu?articleid=10032469 |title=Improved schedules for Dumbarton Express buses go into effect Monday, July 2nd |date=June 21, 2001 |first=Mike |last=Mills |publisher=Alameda-Contra Costa Transit District}} AC Transit again became the service operator in March 2005.

AC Transit introduced a separate Dumbarton Bridge transbay service, route U, on August 29, 2004. Not part of the Dumbarton Express brand, it serves Fremont station rather than Union City station.{{cite press release |url=http://www.actransit.org/news/articledetail.wu?articleid=f5a0c151 |archive-url=https://web.archive.org/web/20050213144452/http://www.actransit.org/news/articledetail.wu?articleid=f5a0c151 |archive-date=February 13, 2005 |title=Cruise from Fremont to Stanford on Line U |date=September 23, 2004 |publisher=Alameda-Contra Costa Transit District}} On December 23, 2007, AC Transit extended its route M over the Dumbarton Bridge to Union City station, replacing route MA (which operated via the San Mateo Bridge).{{cite web |url=http://www.actransit.org/riderinfo/SChange_Dec07.htm |archive-url=https://web.archive.org/web/20080216071347/http://www.actransit.org/riderinfo/SChange_Dec07.htm |archive-date=February 16, 2008 |title=AC Transit Service Changes Effective December 23, 2007 |date=December 2007 |publisher=Alameda-Contra Costa Transit District}} The route M extension was discontinued on March 28, 2010.

By 2009, some reverse-peak trips (eastbound in the morning and westbound in the afternoon) were routed via East Palo Alto and designated DB3.{{cite web |url=http://www2.actransit.org/maps/schedule_results.php?ms_view_type=1&version_id=9&maps_category=2&maps_line=DB3&map_submit=Get+Schedule |archive-url=https://web.archive.org/web/20090820082724/http://www2.actransit.org/maps/schedule_results.php?ms_view_type=1&version_id=9&maps_category=2&maps_line=DB3&map_submit=Get+Schedule |archive-date=August 20, 2009 |title=Line DB3 |publisher=Alameda-Contra Costa Transit District}} On December 19, 2011, route DB3 was discontinued, and MV Transportation replaced AC Transit as the operator of Dumbarton Express service.{{cite web |url=http://www.actransit.org/2011/11/22/minor-service-changes-begin-on-december-18-2011/ |archive-url=https://web.archive.org/web/20111214051916/http://www.actransit.org/2011/11/22/minor-service-changes-begin-on-december-18-2011/ |archive-date=December 14, 2011 |title=Minor service changes begin on December 18 |date=November 22, 2011 |publisher=Alameda-Contra Costa Transit District}}{{cite web |url=http://www.actransit.org/2011/12/15/dumbarton-express-changes-december-19/ |archive-url=https://web.archive.org/web/20120212211446/http://www.actransit.org/2011/12/15/dumbarton-express-changes-december-19/ |archive-date=February 12, 2012 |title=Upcoming Changes to Dumbarton Express Service |date=December 15, 2011 |publisher=Alameda-Contra Costa Transit District}} At that time, the service cost $2.1 million annually to operate, of which fare revenues covered $0.5 million. Service was increased by 80% on July 2, 2012, with service on route DB1 tripled. Route DB was rerouted to terminate at The Oval on the Stanford University campus, while route DB1 was extended to cover part of the former DB route in the Stanford Research Park.{{cite press release |url=http://www.actransit.org/2012/06/12/get-ready-to-experience-expanded-dumbarton-express-service/ |archive-url=https://web.archive.org/web/20120819151833/http://www.actransit.org/2012/06/12/get-ready-to-experience-expanded-dumbarton-express-service/ |archive-date=August 19, 2012 |date=June 12, 2012 |title=Dumbarton Express Service Nearly Doubles on July 2 |publisher=Alameda-Contra Costa Transit District}}

On August 2, 2017, SamTrans released a study that examined the feasibility of adding additional bus routes to the service. The study recommended two new bus routes: an express route traveling between Union City station and Redwood City Caltrain station, and a local route between the Union City BART station to job centers in northern Mountain View and Sunnyvale. The introduction of the two routes was expected to more than double Dumbarton Express ridership. Rail service between Redwood City and Union City on the Dumbarton Rail Corridor is also proposed.{{cite web |url=http://www.samtrans.com/Assets/__Agendas+and+Minutes/SamTrans/Board+of+Directors/Presentations/2017/Dumbarton+Transportation+Corridor+Study+Update.pdf |title=Dumbarton Transportation Corridor Study |date=August 2, 2017 |archive-url=https://web.archive.org/web/20171002224950/https://www.samtrans.com/Assets/__Agendas+and+Minutes/SamTrans/Board+of+Directors/Presentations/2017/Dumbarton+Transportation+Corridor+Study+Update.pdf |archive-date=October 2, 2017 |publisher=SamTrans}}
