Escondido Subdivision

[1] It is primarily used today by the Sprinter hybrid rail and local freight trains serving Escondido industries late at night, after the last Sprinter train of the day is taken out of service.

[2] The North County Transit District, which operates local public transit services, purchased the line from the Santa Fe Railroad in 1992, to operate passenger rail service, which started on December 28, 2007.

Local Santa Fe (later BNSF) freight trains continued to operate over the line until 2008, when the service was contracted out to Pacific Sun Railroad; this practice ended on October 1, 2020, when PSRR's contract with BNSF expired.

For a very short amount of time, NCTD used Coaster Equipment for track repairs.

In 2020, the Pacific Sun railroad stopped service, and freight operations on the line were given back to the BNSF Railway, which also operates freight service on the connecting Surf Line.
