San Diego Trolley

The San Diego Trolley is a modern light rail system serving downtown and suburban areas via three lines on mostly exclusive right-of-way. The Trolley is the currently the nation’s sixth most-ridden light rail system with 53 stations on about 82.2 miles of track. It served approximately 92,100 riders every weekday during the third quarter of 2010.

The Trolley uses three models of distinctive bright-red LRVs manufactured by Siemens. One-way regular adult fare is $2.50, and riders must present proof-of-payment when asked by a fare inspector.

Revenue service started in 1981, and the system’s most recent expansion was the Green line which began operation in 2005. Current projects include new low-floor rolling stock, an 11-mile Mid-Coast line going north to University City, and a vintage streetcar service similar to Muni’s F-Market line in San Francisco.


Blue Line – The Blue Line operates between San Ysidro and Old Town via Chula Vista, National City, and Downtown.

Orange Line – This line operates between El Cajon and Downtown via La Mesa and Lemon Grove.

Green Line – This line operates between Santee and Old Town via San Diego State University. The SDSU Transit Center on the Green Line is notable for being the Trolley’s only underground station.
