The Bayshore Cutoff is the rail line between San Francisco and San Bruno along the eastern shore of the San Francisco Peninsula. It was completed by Southern Pacific (SP) in 1907 at a cost of $7 million, and included five tunnels, four of which are still used by Caltrain, the successor to Southern Pacific's Peninsula Commute service. Fill from the five tunnels was used to build the Visitacion or Bayshore Yard, the main SP classification yard near the city of Brisbane. The Del Monte was similarly rerouted over the line at some point in its operational history.

The Del Monte was a passenger train operated by the Southern Pacific Railroad between San Francisco and Monterey, California. It ran from 1889 to 1971.
