 Trackage within the city of San Francisco was electrified, while the rest of the line was operated with steam locomotives, and later, with self-propelled railcars.Despite significant passenger patronage, especially on weekends, the railroad never recovered from losses in the 1906 earthquake and failed to attract enough freight traffic to cover increasing deficits.A never-built branch would have split from the mainline and run along what is now 19th Avenue, Eucalyptus Drive, 47th Avenue, Rivera Street, and 48th Avenue to Golden Gate Park.
