The North County Transit District (NCTD), branded as North County Transit – San Diego Railroad, is the agency responsible for public transportation in Northern San Diego County, California. The agency manages the COASTER commuter rail service between Oceanside and San Diego, the SPRINTER hybrid rail service between Escondido and Oceanside, the BREEZE transit bus service, LIFT paratransit service, FLEX, and NCTD+ on-demand services.

Established on September 20, 1975, as the North County Transit Development Board, and later took the name North County Transit District (NCTD). The agency's jurisdiction includes Oceanside, Carlsbad, San Marcos, Vista, Escondido, Fallbrook, Pauma, Valley Center, San Dieguito, and Ramona. The Board would serve as the operator of bus service within the North County area, absorbing the municipal bus systems of Escondido and Oceanside.

NCTD owns of mainline railroad track (the Surf Line) from the Orange County/San Diego County line to Santa Fe Depot (used by COASTER, Metrolink, and Pacific Surfliner passenger trains along with BNSF Railway freight trains) along with the Escondido Subdivision (used by the SPRINTER and BNSF freight trains).

NCTD works closely with the San Diego Metropolitan Transit System (MTS), which operates public transit services in Southern San Diego County, and the San Diego Association of Governments (SANDAG), which plans, develops, and constructs transit projects for both NCTD and MTS.

As of , NCTD provides passenger trips per year, or about per weekday as of . NCTD's geographic area is approximately with an approximate population of 842,000 people.

History The North San Diego County Transit Development Board (NSDCTDB) was established in 1976 by California Senate Bill No. 802 to plan, construct, and operate public transit in North San Diego County. The Board quickly acquired the municipal transit systems operated by the cities of Escondido and Oceanside. The Board also designed a regional transit system consisting of local and regional corridor routes to serve the transportation needs of North San Diego County.

In 1982, planning began for the Coast Express Rail (COASTER) commuter rail service. On June 2, 1994, the Board created a non-profit corporation called the San Diego Northern Railway (SDNR) to maintain, enhance, and operate the COASTER. SDNR purchased the tracks to be used by the COASTER from the Atchison, Topeka and Santa Fe Railway in 1994; SDNR was later dissolved in 2002. On February 27, 1995, COASTER service commenced.

On January 1, 2003, Senate Bill 1703 was enacted, transferring responsibility for future transit planning, programming, development, and construction to the San Diego Association of Governments (SANDAG), San Diego's regional planning agency. In 2005, the State Legislature changed NSDCTDB's name to the North County Transit District (NCTD).

In March 2008, after many years of planning, the SPRINTER hybrid rail service began service. FLEX on-demand service began in 2011.

In fiscal year 2009, NCTD projected annual operating deficits of more than $24 million by 2014. In response, NCTD made proactive changes to maintain transit services and related jobs, including reducing staff and renegotiating and restructuring various contracts. These changes closed a five-year, $80 million budget gap. The new business model also allowed NCTD to lower fares, increase service and ridership, and grow its financial reserves.

NCTD relies on public funding. In 1987, voters approved the Proposition A TransNet Ordinance, which provided funding for future transit projects and improvements to the existing system. In November 2004, voters approved a 40-year extension of the TransNet sales tax, which will allow NCTD to continue to operate service for many years.

In August 2018, NCTD announced that they were seeking public opinions and input on a re-brand of the agency. This included a new COASTER paint livery.

The BREEZE Bus Service serves as the main form of public road transportation for residents of North San Diego County. BREEZE service began in 1976 when NCTD acquired the municipal bus systems serving Escondido and Oceanside.

The annual ridership of BREEZE buses is 7.9 million people, with an average weekday ridership of 25,800 people. More than 2,600 bus stops and 9 transit centers service the BREEZE buses. As of April 2025, the fleet comprises 166 vehicles, including 144 compressed natural gas (CNG) buses.

In June 2023, NCTD was awarded $29 million to order 23 hydrogen-electric buses that will help the agency continue to reach its goal of transforming the entire BREEZE fleet to zero-emissions by 2040. Beginning in 2025, exactly one quarter of BREEZE's fleet will be operated by zero-emission buses; 35 hydrogen-electric buses and 6 battery-electric buses.

On October 29, 2024, NCTD officially broke ground on a new hydrogen fueling station at BREEZE's main facility in Oceanside to support hydrogen-electric buses. On that same day, 12 brand new XHE40 buses from New Flyer were delivered to NCTD. The total cost of the hydrogen fueling station will be around $8 million. U.S. Representative Mike Levin secured $1.72 million for the project through the Fiscal Year 2022 federal appropriations bill, while the California Energy Commission funded the station with $6 million of their own. Construction of the hydrogen fueling station is expected to be completed in the summer of 2025.

In November 2009, NCTD approved outsourcing all bus and rail operations effective July 1, 2010, to First Transit. The agency anticipated saving $70 million over seven years with the move. Fleet and facility operators remained NCTD employees until their contracts expired June 30, 2011. On June 29, 2025, NCTD brought all functional contracted bus operations back in house, marking the first time in the agency's history that all Bus and Rail operations were managed directly by the authority since insourcing NCTD's rail in 2022.

As of February 2026, NCTD offers 34 BREEZE bus routes plus 5 FLEX zones.
