Originally at the split of the line from Amsterdam to Harlem and beyond to Rotterdam, and the line from Den Helder and Zaandam to Amsterdam. All tracks and platforms were on an east west orientation. In 1986, service was introduced between Amsterdam CS (Centraal Station) and Schiphol Airport. Selecting a route for this line was a challenge. Amsterdam is a historic old city, close to sea level which makes extensive tunneling difficult. The most practical location for the new line to Schiphol would be at the west edge of Amsterdam, extending south from Sloterdijk station. At Singelgracht Aansluiting (Interlocking), 2 km east of the station, the new line would diverge north, ascend and loop south. And pass over the existing tracks on a north south orientation. In addition a connecting line was built, diverging from the line from Den Helder and Zaandam at Houtrakpolder Aansluiting (Interlocking), 1 km west of the station. And connecting with the line to Schiphol immediately south of the station.
