Coaster (stylized as COASTER) ( reporting mark NCTC) is a commuter rail service that operates in the central and northern coastal regions of San Diego County, California, United States. The service is currently operated by Bombardier Transportation on contract with North County Transit District (NCTD). The service has eight stops and operates primarily during weekday peak periods, with additional weekend and holiday service.
The North San Diego County Transit Development Board was created in 1975 to consolidate and improve transit in northern San Diego County. Planning began for a San Diego–Oceanside commuter rail line, then called Coast Express Rail, in 1982.  Funding for right-of-way acquisition and construction costs came from TransNet, a 1987 measure that imposed a 0.5% sales tax on San Diego County residents for transportation projects.  The Board established the San Diego Northern Railway Corporation (SDNR) - a nonprofit operating subsidiary - in 1994.  SDNR purchased the 41 miles (66 km) of the Surf Line within San Diego County plus the 22-mile (35 km) Escondido Branch (later used for the SPRINTER) from the Santa Fe Railway that year.[ citation needed]
COASTER service began on February 27, 1995.  NCTD originally contracted Amtrak to provide personnel for Coaster trains.  In July 2006, TransitAmerica Services took over the day-to-day operation of the commuter train, based on a five-year, $45 million contract with NCTD.   In 2016, Bombardier Transportation replaced TransitAmerica as COASTER's operator. 
San Diego County voters extended the TransNet sales tax through 2038, which includes funding for rail track upgrades. By the early 2010s, numerous improvements such as added double track and bridge replacements were in various stages of construction and design.  As part of the broader North Coast Corridor project, approximately $1 billion is planned to be spent on new segments of double track between San Diego and Orange County. 
NCTD plans to extend COASTER service north to Camp Pendleton   The agency also plans to build limited-use stations at the Convention Center and the Del Mar Racetrack for use during major events.  
More than 20 COASTER trains run on weekdays,  with additional service on the weekends.  As of the April 3, 2017 schedule, COASTER also added Friday Night service with trains running until a quarter after midnight. More weekend services operate during summer months and when there are special events, such as home games for the San Diego Padres.

The COASTER connects fully with Amtrak's Pacific Surfliner at Oceanside, Solana Beach, Old Town Transit Center, and Santa Fe Depot in San Diego.
The COASTER also connects with the Metrolink rail system at Oceanside, providing connecting service to Orange, Los Angeles, Riverside and San Bernardino counties. It connects to the San Diego Trolley (Green Line) and MTS buses at the Old Town Transit Center; it also connects to the San Diego Trolley (all lines) and MTS buses in the vicinity of the Santa Fe Depot in downtown San Diego – including to the MTS Route 992 bus which offers direct service to Lindbergh Field from Downtown San Diego. Finally, the COASTER connects with BREEZE buses at all North San Diego County station stops (i.e. in Zone 1).
The cost of COASTER tickets is based upon the number of zones traveled (see map). Fare collection is based on a proof-of-payment system: tickets must be purchased before boarding and are checked by roving fare inspectors. Monthly passes are available. All tickets and passes include transfer agreements with NCTD BREEZE buses and monthly passes include transfer with the Metropolitan Transit System (MTS) buses and Trolleys. On January 20, 2011, the NCTD implemented a fare reduction – the fare reduction led to increased ridership on the COASTER and so was made a permanent fare reduction in September 2011. As of September 2019 [update], regular one-way fares are as follows: 
- Within one zone: $5
- Within two zones: $5.75
- Within three zones: $6.50
With proof of eligibility, senior citizens (ages 60 and over), people with disabilities, and Medicare cardholders receive a 50% discount on the above fares.
Riding the COASTER without a valid ticket may result in a penalty fare of up to $250. Riders cannot purchase tickets on board the train.
In September 2008, SANDAG introduced a new contactless "Compass Card", made possible by Cubic Transportation Systems, Inc. The "Compass Card" allows passengers from MTS and NCTD to store regional transit passes and cash value on a rewritable RFID card. Customers can purchase passes and add cash value on the Internet or at any ticket vending machine. Prior to boarding a train, customers tap their Compass Cards on the ticket validator located on the train platform. The LED display on the validator then lights up with lights resembling that of a stoplight, and the LCD display shows text regarding the passenger's fare account.
The COASTER carried about 514,450 passengers during its first year of operation,  and ridership rose steadily in the years that followed. In 2012, COASTER ridership was approximately 1.6 million people, with an average number of 5,600 weekday boardings. 
Approximately 40% of weekday commuters detrain at Sorrento Valley.[ citation needed]

In June 2018, the North County Transit District Board of Directors approved the purchase of five Siemens Charger locomotives to replace their existing five F40PHM-2C locomotives that were remanufactured by Morrison-Knudsen. Deliveries are expected to begin in August 2020, with $10.5 million of the estimated $53.9 million cost earmarked from statewide gas tax and vehicle registration fees.  In June 2019, the North County Transit District Board approved the purchase of two additional Chargers to replace their two existing F59PHI locomotives.  As of July 2020, options for two more locomotives remain on the contract, but have not yet been exercised. 
In July 2020, the Board approved the purchase of eleven new Bombardier BiLevel passenger cars—eight coaches and three cab cars—that will be used to add two trainsets to regular service upon delivery in late 2022.  The order included options for 27 additional cars. 
In August 2018, NCTD announced that they were seeking public opinions and input on a re-brand of the agency, and ran online polls for the public to vote on a new paint scheme and logo for Coaster equipment. 
NCTD maintains two rail yards for the COASTER. The main maintenance and storage yard, located at Stuart Mesa on Camp Pendleton, is just north of the Oceanside station stop. This is where cars are stored for the night and trains are serviced, although due to the small size of the yard, COASTER trainsets are also stored at the nearby Fallbrook Yard when out of service. Tracks 25, 26 and 27 of the San Diego Trolley yard at 12th and Imperial in Centre City San Diego is used to store trains during the midday and for weekday train staging, and is shared with the San Diego Trolley and the San Diego and Imperial Valley Railroad.
