Del Mar racetrack
Additional Amtrak-owned cars are added (up to 12-car consists) during periods of high demand, including the San Diego Comic-Con, the San Diego County Fair, events at the Del Mar racetrack, and after the 2018 Southern California mudflows closed Highway 101. Amtrak Great Dome car "Ocean View" was occasionally used as an additional business class car prior to its retirement in 2019.
