The Metro System Rapid Transit Network
The map below is from the draft (March, 2003) version of MTA's Short Range Transportation Plan. It shows the Metro Red Line (subway), the Metro Blue, Green, and Gold Lines (light rail), Metrolink (SCRRA-operated commuter rail), and Metro Rapid bus lines (excluding the two lines that were added to the program -- 734 Sepulveda and 741 Reseda-Nordhoff -- under the San Fernando Valley North-South Transitway Major Investment Study, which was still pending approval when this map was created; those lines are shown on a later map). The map also shows the route of the El Monte Busway, the Harbor Transitway, planned Metro Rapid-exclusive lanes and possible future light rail extensions.
This second, earlier map illustrates the complete existing Metro Rail system, including the Metro Red Line Segment 2-B to Hollywood/Vine Station, which opened June 12, 1999; Segment 3 to North Hollywood Station, which opened June 24, 2000; the proposed Red Line extensions east from Union Station and west from Wilshire/Western Station (highlighted in yellow, officially suspended in January, 1998; the corridor is again under consideration for a subway extension); the Burbank-Chandler right-of-way, which was used for the Metro Orange Line busway; and the Pasadena Gold Line (shown as dashed blue lines, as it was under construction as an extension of the Metro Blue Line when this map was released). Metrolink lines are shown in purple. This map is included to show the names of all MTA and Metrolink rail stations, although three of the Gold Line stations were changed by the MTA board two months before the line began operation. Those station names are cross-referenced in the June, 2003 service changes report.
The entire Metro Rail system, as originally proposed, had nearly three times the mileage.
(Thanks to David Mieger at MTA for providing the maps.)
The addition of the Gold Line's 13.7 miles in 2003 made the Metro Rail system the fifth largest rail transit system in the United States. The mileage added from the Gold Line Eastside Extension (6 miles) in 2009 and the Expo Line (8.7 miles) in 2012 has brought the total amount of rail mileage to 87.8 miles. The ten largest US urban rail systems (in miles, by agency) are Chicago's "L" (224 track miles), the New York City subway (209 route miles), the San Francisco Bay Area's BART (104), Washington D.C.'s Metro (103), Los Angeles' Metro Rail (88), Boston's "T" (64), the San Diego Trolley (54), Atlanta's MARTA (48), Philadelphia's SEPTA (43), and Cleveland's RTA (37). When the rail projects presently in the active planning and construction process are completed (Purple Line subway extension, Expo Line Phase 2, Gold Line Foothill Extension, Crenshaw/LAX Line, and Regional Connector) the Metro Rail system will comprise 125 miles, which will make it the third largest rail transit system in the country.
The LAX Master Plan includes a proposal to create a new transit hub that includes the Green Line, with a "people mover" from there into Los Angeles International Airport itself.
