S2 (Berlin)

The Berlin S-Bahn is a rapid transit railway system in and around Berlin, the capital city of Germany. It has been in operation under this name since December 1930, having been previously called the special tariff area Berliner Stadt-, Ring- und Vorortbahnen. It complements the Berlin U-Bahn and is the link to many outer-Berlin areas, such as Berlin Brandenburg Airport. As such, the Berlin S-Bahn blends elements of a commuter rail service and a rapid transit system.

The Ringbahn is a 37.5 km (23.3 mi) long circle route around Berlin's inner city area, on the Berlin S-Bahn network. Its course is made up of a pair of tracks used by S-Bahn trains and another parallel pair of tracks used by various regional, long distance and freight trains. The S-Bahn lines S41 and S42 provide a closed-loop continuous service without termini. Lines S45, S46 and S47 use a section of the southern and western ring, while lines S8 and S85 use sections of the eastern ring. The combined number of passengers is about 400,000 passengers a day. Due to its distinctive shape, the line is often referred to as the Hundekopf.

The Berlin S-Bahn began on 8 August 1924 with the first section from Stettiner Vorortbahnhof to Bernau using steam locomotives. On 13 August 1961 it was broken up when the Berlin Wall was built, resulting in two sections: the eastern part and the western part. The western part experienced a massive strike which resulted in closure of several stations, after declining use. Attempts were made to reopen at various times but in the end, only three lines were finally opened after the strike. Since 9 November 1989, when the Berlin Wall was opened, the Berlin S-Bahn began to expand rapidly with their budgetary costs.
