# Green Line (San Diego Trolley)

The Green Line is a 19.8-mile (31.9 km) light rail line in the San Diego Trolley system, operated by San Diego Trolley, Inc. an operating division of the San Diego Metropolitan Transit System (MTS). The route serves downtown San Diego, Mission Valley, and the cities of La Mesa and El Cajon. The Green Line has the second highest ridership of the San Diego Trolley's three core lines, transporting 13,673,926 riders during FY 2014 - according to MTS.
The line is one of five lines in the trolley system, the others being the Blue, Orange, Copper, and Silver ("heritage weekend" service only) lines.

## History

The Green Line is the third line in the San Diego Trolley system, with service beginning on July 10, 2005 along with the completion and opening of the 5.9 miles (9.5 km) Mission Valley East extension.
The line primarily operates on this extension as well as a segment previously served by the Blue Line between Old Town and Mission San Diego. It traverses Mission Valley and the San Diego River corridor for this segment.
During a system redesign which took effect on September 2, 2012, as part of the Trolley Renewal Project, the western portion of the Green Line was extended from Old Town south through downtown and along the Bayside Line, terminating at 12th & Imperial Transit Center's Bayside Platform. This redesign allowed for two "universal" transfer points among all three core lines: the 12th & Imperial Transit Center and Santa Fe Depot Transit Center (which consists of Santa Fe Depot, America Plaza, and Courthouse stations, as well as the Santa Fe Depot/America Plaza Rapid terminal).
In May 2024, MTS announced that a new service, known as the East County Connector (and later the Copper Line), would replace the Green and Orange lines between El Cajon Transit Center and the eastern terminus at Santee. The proposal was prompted by service issues caused by the merge of the double track to a single track between the final two stations, creating delays for Green Line trolleys waiting for the track to clear. On September 29, 2024, Green and Orange Line service was cut back to El Cajon Transit Center, and service on the Copper Line began.
The Green Line's SDSU Transit Center is the only underground station in the entire trolley network.

### Naming rights

In October 2017, Sycuan Casino secured the naming rights for the Green Line when the MTS had sought out to sell out the naming rights for each line in the trolley system. The line was then named the Sycuan Green Line. However, this is no longer the case. The Green Line is home to a paid station naming sponsorship, with the former Alvarado Medical Center station being known as UC San Diego Health East station.
