Due to the fact that neither San Diego nor Goleta is equipped with a roundhouse or a turntable, trains running on the Pacific Surfliner are arranged so that the last car is one equipped with engineer controls, so that the train can be operated in either direction, allowing for a quick turnaround.
Under the Atchison, Topeka, and Santa Fe Railroad, and later under Amtrak until the late 1990s, this same service was called the San Diegan.
