Layout and Distances
Metro was the only rapid-transit system in the world with a "pretzel" configuration in which a line crosses over itself and trains pass through the same station twice at different platforms, as Yellow line trains do at Monument Station. It was joined by the Vancouver SkyTrain in Canada and the RandstadRail tram system in the Netherlands in 2006. Toronto had previously experimented with a pretzel configuration in 1966.
Distances on the system are measured from a datum point at South Gosforth. The system is metric, with distances in km to the nearest m. Lines are designated In and Out. The In line is from St. James to South Shields via the inside of the loop (Yellow Line); the Out line is the opposite. By extension the In line is from Airport to South Gosforth, and from Pelaw to Sunderland and South Hylton. Distance plates are mounted on all overhead line structures. Different distances are normally quoted for stations, depending on whether the direction of travel is In or Out. Distances increase from the datum in all directions.
The part of the Sunderland extension owned by Network Rail is dual-marked in metric units and the miles and chains system used by mainline trains. The boundary between the two systems is close to Pelaw Metro Junction. The closest adjacent stations are St Peter's and Sunderland; the furthest apart Pelaw and Fellgate.

Famous quotes containing the word distances:
“We then entered another swamp, at a necessarily slow pace, where the walking was worse than ever, not only on account of the water, but the fallen timber, which often obliterated the indistinct trail entirely. The fallen trees were so numerous, that for long distances the route was through a succession of small yards, where we climbed over fences as high as our heads, down into water often up to our knees, and then over another fence into a second yard, and so on.”
—Henry David Thoreau (1817–1862)
