Green Line (Los Angeles Metro)

Map showing Green Line route and stations

The entire route of the Green Line is grade-separated, with its tracks following a fully elevated route, either on a guideway or in the median of the Century Freeway (Interstate 105). The line begins in the west at Redondo Beach station, then heads roughly north through El Segundo. At Aviation/LAX, passengers can transfer to any one of several bus lines from different operators, particularly Shuttle Bus "G", a shuttle bus from the Green Line to LAX. From here, the Green Line heads east in the median of the Century Freeway, with a connection to the Metro Silver Line bus rapid transit line at the Harbor Freeway Station. It then continues to a major transfer connection at the Willowbrook Station (transfer point to the Metro Blue Line). Finally, the line terminates in the city of Norwalk, just east of the 605 Freeway.

Metro Green Line trains run between approximately 3:30 a.m. and midnight daily.[5] Service on Friday and Saturday nights continues until approximately 2:15 a.m. First and last train times are as follows:

To Norwalk Station

Eastbound

• First Train to Norwalk from Willowbrook/Rosa Parks Station: 3:33 a.m.
• First Train to Norwalk from Douglas Station: 3:41 a.m.
• Last Train to Norwalk: 11:59 p.m. (2:01 a.m. Friday and Saturday nights)

To Redondo Beach Station

Westbound

• First Train to Redondo Beach Station: 4:04 a.m.
• Last Train to Redondo Beach Station: 12:50 a.m. (2:12 a.m. Friday and Saturday nights)

Trains on the Green Line operate every seven to eight minutes during peak hours Monday through Friday. They operate every 15 minutes during the midday and all day on the weekends, with night service running every 20 minutes.[5]

Operating plan approved for the Crenshaw/LAX Line

The Crenshaw/LAX Line project extends from the existing Green Line, and the question of how the new segment would be integrated into the Metro Rail system was the subject of some controversy in 2018 as completion of the project loomed. Early proposals had suggested that a new line would operate between Expo/Crenshaw station in the north and Aviation/Century in the south, or possibly extend to Redondo Beach station once the stations west of Aviation/LAX station could accommodate 3-car trains, with the stretch southwest of the wye continuing to be served by the Metro Green Line as well.[8] An additional service would have connected Norwalk to the new Aviation/Century station and planned 96th Street Transit station and the Airport Metro Connector.[9]

But this would require trains passing all three directions through the wye connecting the new and existing infrastructure, which Metro staff felt would unduly wear down the points. Instead, in 2018 Metro proposed a service plan that would see the newly opened segment connected to the bulk of the current Green Line; the southwest segment of the Green Line in the South Bay would operate as a separate shuttle between Redondo Beach and the new Aviation/Century station. The arrangement was meant to provide a seamless rail option for the many passengers who currently transfer between the Green Line and north-south bus lines in the area, as well as operationally combine the Norwalk-LAX and Crenshaw/Expo-LAX legs, which have matching capacity needs, rather than combining either with the more sparsely used Redondo Beach leg.[10]

However, the plan was met with resistance from some board members, particularly Supervisor Janice Hahn, because it would require South Bay passengers to make multiple transfers to complete trips currently possible with only one transfer.[11] A faction of the Metro board led by Hahn proposed a one-year pilot of an alternative routing scheme under which one line would travel from Norwalk to Expo/Crenshaw and another from Redondo Beach to Willowbrook/Rosa Parks. The proposal, dubbed C-3, was approved by the Metro board on December 6, 2018.[12] This option will entail an additional $10 million annual operating cost over Metro's initial proposal, in large part because a substantial segment of the current Green Line between Willowbrook and Aviation/LAX will see three-minute headways at peak hours. The adopted proposal will also limit the potential length of trains on the new segment to two cars due to power constraints, and will preclude a one-seat ride from the South Bay to LAX,[13] but will maintain the ability of South Bay passengers to transfer directly to the Silver and Blue Lines.

The future South Bay Green Line extension will extend the Metro Green Line from these stub tracks at the southern end of the Redondo Beach station to Torrance.

Metro is currently working on the initial environmental study of a corridor extension of the C Line from its Redondo terminus toward the southeast. The "South Bay Metro C Line Extension" would roughly follow the Harbor Subdivision ROW into the South Bay, to the Torrance Regional Transit Center (RTC).[14]

Metro and the public are considering two alternatives in the DEIR: an elevated light-rail extension, and an at-grade extension over existing tracks, with vehicle type still to be determined. Study of the South Bay Extension will lead to publication of a Draft Environmental Impact Report (DEIR). The study was expected to be completed in 2011. Project was placed on hold in Spring 2012 due to uncertain funding. With the passage of Measure M in 2016, $619 million was cited for the Green Line Extension south and the study resumed. The (EIR/EIS) resumed, which is currently scheduled for mid 2020 release.[15]

Metro authorized two of four alternatives to move forward. Alternative #1 and Alternative #3. Metro staff recommended the two alternatives into the DEI/EIS status for further analysis and refinement in September 2018. The study area includes the former Harbor Subdivisions right of way. The extension study includes the Redondo Beach station to the Torrance Transit Center, a 4.5 mile extension study area.[16]

The following table shows all potential metro stations, and the alternatives for which they apply:

Station Options	Alt 1	Alt 2	Connecting Rail/Bus Service	Community
Redondo Beach station (already built)	×	×	Crenshaw/LAX Line	Redondo Beach
Redondo Beach Transit Center station	×	–	Beach Cities Transit	Redondo Beach
South Bay Galleria station	–	×		Redondo Beach
Torrance Transit Center station	×	×	Torrance Transit	Torrance

According to the LA County Expenditure Plan (Measure M), groundbreaking for the project is currently scheduled for 2026, with expected opening in 2030–2033. The timeline is expected to be accelerated under the Twenty-eight by '28 initiative.[17]

The Green Line's eastern terminus suffers from the fact that it stops two miles (3 km) just short of the heavily used Norwalk/Santa Fe Springs Metrolink station, where several Metrolink lines operate. Local bus service is provided between the Metrolink station and the Green Line terminus, but schedules are not coordinated with the Green Line arrivals. While plans exist to close the gap,[18] any potential funding is currently years away.[19]

The Green Line is operated out of the Division 22 Yard (Aviation Street Yard) and the Division 16 Yard (Southwestern Yard). These yards stores the fleet used on the Green line. Light maintenance is done on the fleet in Division 22 where as heavier maintenance is done in Division 16. Division 22 is located between Redondo Beach and Douglas stations. Trains enter the yard via a junction halfway between the two stations. Douglas bound trains (Northbound) may enter but there is no exit track to continue North. Redondo Beach bound trains (Southbound) may enter and exit the Yard to continue south. Division 16 is located on the completed section of the Crenshaw/LAX Line in Westchester.

At the time the Green Line opened, the line used rolling stock made by Nippon Sharyo similar to those used on the Metro Blue Line. In late 2001, the Nippon Sharyo P2020's were transferred to the Blue Line, and the Green Line received new Siemens P2000 railcars which have been operating on the Green Line ever since. Kinkisharyo P3010 trains are also used. Trains are limited to two-car sets due to limitations at some stations along the line.[20]
