Los Angeles Metro Rail

Metro Rail has been extended significantly since it started service in 1990, and several further extensions are either in the works or being considered. In 2025, the system had a ridership of 68,764,300 or about 227,800 per weekday as of the second quarter of 2026. Metro Rail operates the busiest light rail system in the United States.

Los Angeles had two previous rail transit systems, the Pacific Electric Red Car and Los Angeles Railway Yellow Car lines, which operated between the late 19th century and the 1960s. The Metro Rail system uses many of their former rights of way, and thus can be considered their indirect successor.

Current system

Lines

In Los Angeles Metro terminology, common with most other metro systems, a line is a named service, defined by a route and set of stations served by trains on that route. (The word does not refer to a physical rail corridor, as it does in New York City Subway nomenclature.)

Metro also uses the same line letter naming system for its Metro Busway services (which are bus rapid transit routes operating in transitways).

Six Metro Rail lines operate in Los Angeles County:

The B and D lines follow a fully underground route, and the C Line follows a fully grade-separated route. The A, E, and K lines run in a mix of environments, including at-grade in an exclusive corridor, street running, elevated, and underground.

Two of the light rail lines (A and E) share tracks between Pico and Little Tokyo/Arts District, while two others (C and K) share tracks between the LAX/Metro Transit Center and Aviation/Century. The two rapid transit lines (B and D) share tracks between Wilshire/Vermont and Union Station.

Stations

The Metro Rail system consists of 110 stations. Metro Rail light rail stations are at ground level, elevated, trenched, or fully underground. All rapid transit stations are fully underground.

Stations include at least two ticket vending machines, wayfinding maps, electronic message displays, and bench seating. Call boxes are available at stations to allow employees at the Metro Rail Operations Control Center to assist passengers with concerns. Unique artwork is integrated into every station, showcasing local culture and improving the aesthetic of the system.

Street-level stations are typically simpler with platforms designed with shade canopies, separated from nearby roads and sidewalks, where passengers can purchase fares and board a train. Free or paid park and ride lots are available at 44 stations and most have bike storage available.

Underground stations are typically larger with a mezzanine level for fare sales and collection above a platform level where passengers board trains. Underground stations and tunnels are designed to resist ground shaking that could occur at a specific location. There is no general magnitude of an earthquake that the entire system is expected to withstand. However, the Metro Rail system has not suffered any damage from earthquakes since its opening in 1990.

Metro Rail uses a proof-of-payment fare system, with Metro's fare inspectors randomly inspecting trains and stations to ensure passengers have a valid fare product on their electronic fare TAP card. When passengers enter a station, they encounter TAP card validators which collect fares when a customer places their card on top. Additionally, fare gates (turnstiles) connected to TAP card validators are at all underground stations, all elevated stations, and some surface stations. Once passengers pass these validators or board a train, they have entered the "fare paid zone", where fare inspectors may check their TAP card to ensure they have a valid fare. Passengers who fail to comply may be penalized and removed from the system.

Rolling stock

Metro Rail maintains two distinct systems of rail: a light rail system and a rapid transit (subway) system, which use incompatible technologies, even though they both use 4 ft 8+1⁄2 in (1,435 mm) standard gauge and use 750 V power. Metro's rapid transit lines are powered by third rail, whereas its light rail lines are powered by overhead catenary. Also, the two separate systems have different loading gauge, and platforms are designed to match the separate car widths.

Hours of operation

The Los Angeles Metro Rail system runs for about 19 hours each day between 5:00 am and 11:45 pm. Limited service on particular segments is provided after midnight and before 5:00 am. There is no rail service available between 2:00 am and 3:30 am except on special occasions such as New Year's Eve. Before the COVID-19 pandemic in March 2020, service operated until approximately 2:00 am on Fridays and Saturdays. The Saturday service after midnight was ended during the pandemic to accommodate train cleaning during those hours.

Service frequency was increased in December 2023 when pandemic conditions were ending. Trains operate more frequently during weekday peak hours and less at other times. During peak hours, the light rail A and E lines run every 8 minutes and the light rail C and K lines run every 10 minutes. The light rail lines operate on 10-minute headways during off-peak periods and weekends. As of April 2026, service frequency was increased on the B and D rapid transit lines with 10-minute headways throughout the day. During early morning hours on weekends and late night hours every day, train frequency on all lines is reduced to every 20 minutes.

Metro plans to increase train frequencies, proposing to further reduce headways on the B, C, D, and K lines in 2025.

Fares and fare collection

The standard Metro base fare applies for all trips. Fare collection is based on a partial proof-of-payment system. At least two fare machines are at each station. Fare inspectors, local police, and deputy sheriffs police the system and cite individuals without proof of payment. Passengers are required to purchase a TAP card to ride Metro Rail. Passengers using a TAP card can transfer between Metro routes for free within 2 hours from the first tap.

Metro introduced daily and weekly fare caps in July 2023, replacing upfront daily and weekly passes, while monthly passes were discontinued outright. With fare capping, the cost of each trip is credited towards the cost of a daily or weekly unlimited pass, automatically ensuring that all passengers pay the lowest fare possible. Due to this, passengers will never pay more than $5 (3 rides) in a day or $18 (11 rides) within seven days; rides are free once the cap is reached. Discounted or free fares are available for seniors, disabled individuals, Medicare recipients, low-income individuals, and students.

The following table shows Metro fares, effective July 1, 2023 (in US dollars):

TAP card and fare gates

Metro has implemented a system of electronic fare collection using a stored-value smartcard called the TAP card. This card was intended to simplify fare collection and reduce costs. In 2012, paper monthly passes were phased out and replaced with the TAP Card. As of September 2013, first-time Metro riders must deposit an additional $2 (or $1 at TAP vending machines) on top of their first fare payment to obtain a reloadable TAP Card. In addition, in 2008 Metro began installing fare gates at all underground stations, all elevated stations, and some surface stations. Implementation of both programs (the TAP Card and the fare gate program) has turned out to be expensive ($154 million in total, so far) and its initial rollout was problematic.

Ridership

In 2025, the Metro Rail system had a ridership of 68,764,300.

As of the second quarter of 2026, the combined Metro B and D lines averaged a weekday ridership of 68,400, making it the ninth busiest rapid transit system in the United States. Taking overall track length into consideration, Metro Rail's rapid transit lines transport 7,960 passengers per route mile, making this the fifth busiest U.S. rapid transit system on a per mile basis, yet at just 70% of pre-pandemic ridership levels. Metro's light rail system is the second-busiest in the United States with 159,400 average weekday boardings as of the second quarter of 2026. In terms of route length, Metro's light rail system is the largest in the United States.

Security and safety

Half of the Metro Rail's trains and stations are patrolled by the Los Angeles County Sheriff's Department under a law enforcement contract. The Los Angeles Police Department and Long Beach Police Department patrol stations within their respective cities, also under contract. The system is monitored by security personnel through closed-circuit television cameras. Metro Ambassadors are an in-house outreach team to provide a better user experience. They help riders navigate and provide information about the system.

In June 2024, the Metro Executive Board voted 10-0 to create their own transit police force. A cited reason included frustration with a lack of control over the existing contracts. This force is planned to consist of officers, crisis workers, and homelessness outreach teams.

History

In the early 20th century, Southern California had an extensive privately owned rail transit network with over 1,000 miles (1,600 km) of track, operated by Pacific Electric (Red Cars) and Los Angeles Railway (Yellow Cars). However, from 1927 revenue shortfall caused Pacific Electric to begin replacing lightly used rail lines with buses. In 1958, the remnants of the privately owned rail and bus systems were consolidated into a government agency known as the Los Angeles Metropolitan Transit Authority or MTA. By 1963, the remaining rail lines were completely removed and replaced with bus service.

In the following decades, growing traffic congestion led to increased public support for rail transit's return. Beginning in the 1970s, a variety of factors, including environmental concerns, an increasing population, and the price of gasoline led to calls for mass transit other than buses. Los Angeles Metro began construction of the initial lines throughout the 1980s using revenues from a voter-approved increase in sales tax. The Blue (A) Line opened on July 14, 1990, 27 years after the final streetcar line closed. The system has been progressively expanded since. The following table shows this expansion's timeline:

Just before the opening of the Metro Rail, Proposition U passed, which halved the allowable residential density throughout much of Los Angeles. This reduced the viability of the Metro Rail by limiting dense residential housing near transit stations. Before 2000, none of the land near the stations was converted to residential use.

Planned expansion

Metro has worked to plan and prioritize project funding and implementation. Metro's 2009 Long Range Transportation Plan (LRTP) was developed to provide a long-term vision of transportation system development for the next 30 years. Metro worked to update the 2009 LRTP citing new housing trends and fiscal changes. Metro released the updated LRTP in 2020.

Beginning in 2014, Metro saw its ridership numbers begin to decline. Many explanations exist for the decline, including safety concerns, an increase in ride-hailing service usage, low-income housing opportunities drying up in L.A. because of the increase in rents, and a shortage of housing. Ridership declines also coincide with passage of AB 60, signed into law by Governor Jerry Brown in 2013, which provides for issuance of a driver's license regardless of immigration status.

The fiscal changes are the passage of Measure R, a countywide incremental sales tax increase passed by voters in 2008, providing funding for many of the highest priority projects in the LRTP. On November 6, 2012, Metro attempted to pass Measure J, but failed as it did not reach the two-thirds majority needed to pass. In the November 2016 election, Metro decided to place another sales tax on the ballot. The voters then approved Measure M, a half-cent permanent sales tax increase to fund many local projects, including Metro Rail expansion.

In 2018, Metro approved renaming its rail lines using a letter-based scheme, similar to those in New York City. Metro recommended the opening of the refurbished A Line in 2019 as a starting point to rename the lines, and then continuing with the opening of the K line, finishing in time for the opening of the Regional Connector in 2023.

LA Metro also plans to expand Union Station tracks and service. Metro has proposed "Link Union Station" to extend tracks 3-10 as run thru tracks. Phase one is to be completed by 2028. Other phases include adding a California High-Speed Rail platform area, a Southeast Gateway line terminus station, and renovate the concourse areas.

Current and priority projects

The following rail projects have been given high priority by Metro. They all appear in the 2009 LRTP constrained plan, and all have funding earmarked from Measure R. With the passage of Measure M in 2016, Metro released an updated Long Range Transportation Plan in February 2017, and released a full report in 2020, along with its Twenty-eight by '28 initiative.

Other expansion concepts

Metro's Long Range Transportation Plan was published in 2009, and was updated in 2020. The following proposed line/system expansions do not have funding or high priority in Metro's long-range plans. Some are listed as "strategic unfunded" in the last Long Range Transportation Plan, indicating some possibility they could be constructed should additional funding materialize. Others have been the subject of Metro Board discussion, with the possibility of future feasibility studies. (More information on each project can be found in the references.)
