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. 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 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 daily, weekly, and monthly passes. 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):
Ridership In , the Metro Rail system had a ridership of . As of , the combined Metro B and D lines averaged a weekday ridership of , 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 average weekday boardings as of . 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 ==
