Following heavy damage during World War II, limited services to the main station were resumed, but then suspended in 1951. In 1957, with the railways to West Berlin under the control of East Germany, Lehrter Bahnhof was demolished, but Lehrter Stadtbahnhof continued as a stop on the S-Bahn. In 1987, it was extensively renovated to commemorate Berlin's 750th anniversary. After German reunification it was decided to improve Berlin's railway network by constructing a new north–south main line, to supplement the east-west Stadtbahn. Lehrter Stadtbahnhof was considered to be the logical location for a new central station.
