San Diego River Double Track
The San Diego River Double Track (SDRDT) project will add a second main track from Tecolote Road to just north of the Old Town Transit Center. The new 0.9 mile track will connect to existing double track at each end, resulting in a continuous seven-mile double track segment for the southernmost portion of the LOSSAN coastal rail corridor from Garnet Avenue/Balboa Avenue to the Santa Fe Depot. The project includes double tracking across the San Diego River with a new double track bridge, construction of associated site improvements, and signal modifications.
The project is located in the City of San Diego within the right-of-way owned by the Metropolitan Transit System (MTS) on tracks managed and operated by the North County Transit District (NCTD).
Concurrent with this project, SANDAG is constructing the Mid-Coast Corridor Transit Project, an 11-mile extension of the San Diego Trolley within the same MTS right-of-way. SANDAG is coordinating closely between the two projects to ensure smooth construction and effective use of space and resources. The SDRDT project is being constructed with sensitivity toward the natural resources of the San Diego River.
This project is necessary to support growth in the LOSSAN coastal rail corridor while increasing reliability and maintaining safety. The existing single track negatively affects reliability of rail service in the corridor. Double tracking allows two trains traveling in opposite directions to pass without slowing or stopping. This results in reduced travel time, improved operational flexibility, and decreased potential for delays.
Amtrak and NCTD plan to increase the number of passenger trains along the LOSSAN Corridor. This project will help to meet the expected increase in demand for railroad operations through this segment of the LOSSAN Corridor, enhance railroad operational flexibility and schedule reliability, facilitate future increases in capacity, and achieve a good state of repair in this segment of the railroad.
