The L Line and Gold Line[2] are former designations for a section of the current Los Angeles Metro Rail system, a single light rail line of 31 miles (50 km)[1] that provided service between Azusa and East Los Angeles via the northeastern corner of Downtown Los Angeles, serving several destinations and neighborhoods, including Little Tokyo, Union Station, the Southwest Museum, Chinatown, and Old Pasadena.

[1] In October 2020, the line was broken into two disconnected segments with the closure of the Little Tokyo/Arts District station in preparation for the opening of the Regional Connector tunnel.

After this station, the line continued west, crossing over the San Gabriel River and underneath the I-605 freeway, diverging from I-210 and entering Duarte, before stopping at Duarte/City of Hope station located on the north side of Duarte Road, across from the City of Hope National Medical Center.

From here, the route continued, with a handful of stations serving the hillside communities north of downtown, including Lincoln Heights, Mount Washington, the Southwest Museum of the American Indian.

Northeast of Chinatown, the line crossed over the Los Angeles River on an elevated viaduct.

At Union Station, passengers could transfer to the B and D rapid transit lines, Metrolink commuter rail, Amtrak, and buses.

[6] The entire section of the line north of Union Station followed the current and former right-of-way of the Pasadena Subdivision.

Prior to this date, riders seeking to travel between the then disconnected segments of the L Line had to use a temporary bus shuttle to make the connection.

The L Line was particularly slow through the Highland Park area, where trains reach speeds of only 20 mph (32 km/h) while operating in a street running section on Marmion Way.

Following the extension to East Los Angeles in 2009, the line's ridership increased to almost 30,000 daily boardings.

Much of the L Line's right-of-way through the San Gabriel Valley was built by the Los Angeles and San Gabriel Valley Railroad in 1885, eventually taken over by the Atchison, Topeka and Santa Fe Railway, as part of the Pasadena Subdivision,[14] which saw Amtrak service until 1994, when construction began on the conversion to light rail.

The southern (Pico/Aliso–East LA) segment was combined with the previously existing E Line, which ran between Downtown Los Angeles and Santa Monica.

[4] After the Regional Connector opened, the L Line became the first letter designation on the Los Angeles Metro Rail system to be permanently discontinued.

The L Line was operated by the Los Angeles County Metropolitan Transportation Authority (Metro).

Division 11 is situated at the end of 208th Street between I-710 and the Los Angeles River in North Long Beach within the A Line.
