context_page_description: 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 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 original alignment of the Coast Line completed in 1863 took it around the western side of San Bruno Mountain, through Colma and Daly City. Rail traffic along the original route needed helper engines for grades and curves along a route nearly 13 miles long. The Bayshore Cutoff reduced the distance to 10.5 miles with a maximum grade of 0.3 percent.
  Once the Bayshore Cutoff was completed, and main line traffic was shifted to it, the former route was renamed the Ocean View line and became a branch. It was used to carry coffins to Colma; it was severed in the 1940s, but a few miles at the south end was still in SP's 1996 timetable.
context_section_description: The Southern Pacific Railroad Bayshore Roundhouse, at the junction of Industrial Way and Bayshore Ave. in Brisbane, California, was listed on the National Register of Historic Places in 2010.
  The Bayshore Roundhouse was completed in 1910 and still stands, although it was damaged in an October 2001 fire which destroyed approximately half the roof. Construction on the Roundhouse started in 1908, shortly after the Bayshore Cutoff was completed, and it was one of the first buildings at the new Bayshore railyard.
  The Roundhouse encompasses an arc of 108 degrees, and has an inner radius of 125 feet (38 m) and an outer radius of 212 feet (65 m). It has forty stalls, and an on-site powerhouse, north of the Roundhouse, provided steam for locomotive use, burning coal from a bunker 600 feet (180 m) long. Seventeen of the stalls (numbered #24 to #40, clockwise) were inside the building and covered. Stalls #1 to #23 were outside whisker tracks, although construction plans, contemporary articles, and the presence of foundation pilings suggest the roundhouse was originally designed to enclose these as well. The wall adjacent to stall #40, on the eastern side of the building, contains four sets of windows, and the outer circumference of the building has two sets of windows for each stall. There is one fire wall (between stalls #32 and #33) without windows (which stopped the 2001 fire from destroying the roof of stalls 33-40), and the wall adjacent to stall #24 does not have windows, since it was originally intended to serve as a second interior fire wall.
  As originally constructed, the turntable was pneumatically operated with a diameter of 80 feet (24 m). The turntable was enlarged to 110 feet (34 m) in 1941 using steel salvaged from the Pajaro River bridge; with the enlargement, the Roundhouse was capable of handling SP's largest steam locomotives. The fire in 2001 destroyed the roof covering stalls #24 through #32. Today, it is the last standing brick roundhouse in California, and it was added to the National Register of Historic Places in 2010.
