The Blue Line is one of five lines in the trolley system, along with the Orange, Green, Copper, and Silver ("heritage weekend" service only) lines. Among them, the Blue Line has the highest ridership, transporting 24,389,986 total riders, or 75,160 per day, in fiscal year 2024. Its sponsored name is due to a $30 million naming rights deal with UC San Diego Health.{{cite magazine |url=http://www.metro-magazine.com/management-operations/news/294836/san-diego-mts-teams-with-uc-san-diego-to-rename-blue-line-trolley |title=San Diego MTS teams with UC San Diego to rename Blue Line Trolley |magazine=Metro Magazine |date=July 17, 2015 |access-date=2016-04-17}} An extension to its namesake campus of the University of California, San Diego, as well as nine other stations, opened to revenue service on November 21, 2021.{{cite news |last1=Luczak |first1=Marybeth |title=San Diego's Mid-Coast Trolley Extension Project Advances |url=https://www.railwayage.com/passenger/light-rail/san-diegos-mid-coast-trolley-extension-advances/ |access-date=9 July 2021 |agency=Railway Age |date=30 June 2021}}{{cite news |date=November 21, 2021 |title=It's finally here: Riders take first trips on trolley extension with 9 new stops |url=https://fox5sandiego.com/news/local-news/its-finally-here-riders-take-first-trips-on-trolley-extension-with-9-new-stops/ |work=Fox 5 San Diego |location=San Diego |access-date=November 21, 2021}}

History

The initial line in the San Diego Trolley system, the Blue Line first opened between Centre City San Diego and San Ysidro on July 26, 1981,{{Cite web |date=2013 |title=MTS Historical Timeline |url=http://www.sdmts.com/MTS/timeline.asp |access-date=June 29, 2013 |publisher=San Diego Metropolitan Transit System}}{{Cite news |last=Ristine |first=Jeff |date=July 23, 2006 |title=After 25 years, the trolley keeps on moving |url=http://www.utsandiego.com/uniontrib/20060723/news_1m23trolley.html |url-status=dead |archive-url=https://web.archive.org/web/20121009114815/http://www.utsandiego.com/uniontrib/20060723/news_1m23trolley.html |archive-date=October 9, 2012 |access-date=June 14, 2009 |work=The San Diego Union-Tribune }} at a cost of $86 million (equivalent to ${{Inflation|US|86|1981|r=0}} million in {{Inflation-year|US}}), using the existing tracks of the San Diego and Arizona Eastern Railway, which the Metropolitan Transit Development Board had purchased from Southern Pacific on August 20, 1979, for $18.1 million (equivalent to ${{Inflation|US|18.1|1979|r=0}} million in {{Inflation-year|US}}).{{Cite web |date=April 2013 |title=San Diego & Arizona Eastern Railway Fact Sheet |url=https://www.sdmts.com/sites/default/files/attachments/SDAEFactSheet.pdf |url-status=live |archive-url=https://web.archive.org/web/20211108120841/https://www.sdmts.com/sites/default/files/attachments/SDAEFactSheet.pdf |archive-date=November 8, 2021 |access-date=March 31, 2021}}

In 1986, the line was named the South Line to differentiate it from the new East Line to Euclid Avenue, which later became the Orange Line. On July 2, 1992, the line was extended north from downtown with the opening of County Center/Little Italy station. It was renamed the North-South Line when the Old Town extension opened on June 16, 1996. The North-South Line was renamed the Blue Line in 1997, with the opening of the extension to Mission San Diego on November 23, 1997.

When the Green Line was brought into service in 2005, the Blue Line was cut back to Old Town Transit Center. At rush hours, however, some Blue Line trains continued onto Qualcomm Stadium; and from Qualcomm Stadium onto San Ysidro. On September 3, 2006, the rush hour service Blue line trains were discontinued entirely, due to duplication of service with Green Line service. All Blue Line trains then terminated at Old Town. Rush hour Blue Line trains operated from San Ysidro to America Plaza with some serving the Bayside.

Blue Line service also experienced some change in the stations served. The San Diego Square station located between 7th and 8th Avenues in downtown closed in 1986 due to low ridership and its close proximity to Fifth Avenue station. Later that year, E Street station in Chula Vista opened in October 1986, about five years after service already operated along the tracks served. At the same time, the Centre City station on C Street, between Sixth Avenue and Fifth Avenue, was renamed Fifth Avenue station. Fenton Parkway station was an 'infill' station that opened in 2000; however, it, like the rest of the stations on the route to Mission San Diego, is now only served by the Green Line.

The Mid-Coast Corridor Transit Project was done in conjunction with the North Coast Corridor project, which upgrades the LOSSAN Corridor further to the north. Both projects build upon the original right-of-way of the Surf Line, which was built in the 1880s as the original railway from Los Angeles to San Diego.
