Tierpark (Berlin U-Bahn)

Prior to the opening of the station, the line was intended to go to Karlshorst in the early 1950s/60s plans.

It was the one and only subterranean U-Bahn station to be built by the East German government.

[1] The new plan was to extend the route beyond the Tierpark extension to Oberschöneweide, very near to Treptow.

In the 1980s, a new plan was developed to run along the VnK Railway to Kaulsdorf, and to create a new stretch as far as Hönow, removing the need to go to Oberschöneweide and Marzahn.

The new route was supposed to be opened in two phases, ending in 1988, to replace the terminus of the former Line E. Construction began on 1 March 1985, with the first to open being Biesdorf-Süd and Elsterwerdaer Platz, and then on to Hönow by 1 July 1989, just a few months before the fall of the Berlin Wall.
