The Berlin Ringbahn is a 37-kilometer-long railway line that surrounds the inner city of Berlin as a closed ring. It has two tracks for the S-Bahn and others, which are used in sections for long-distance, regional and freight traffic, and is connected to the light rail, which runs in an east-west direction within the ring, and several lines running radially towards the city center. Around 1,100 train journeys take place on the S-Bahn tracks every day, transporting over half a million passengers. In 2018, the section between Treptower Park and Ostkreuz, with around 170,000 passengers a day, was one of the busiest sections of the Berlin S-Bahn. The distinctive shape of the circular line is also known as the dog's head or the big dog's head. This term has even entered the parlance of politics in Berlin. The area enclosed by the Ringbahn (with an area of approx. 88 km²) is also of administrative importance: The area within and including the Ringbahn forms the Berlin tariff zone A of the Berlin-Brandenburg transport association. The Stations at the S41,S42 "Ringbahn": Rolling Stock is the BR480 and BR 481/482 The DB BR480: The DB BR 481/482
That's a great suggestion and it would be something new to TS and TSW because there is no route that runs around in the games and it would be so fun going all day around Berlin
If added to the game this should be the first German S-Bahn route not to use 15kv 16.7hz like Rhein-Ruhr Osten Haputstrecke Rhein-Ruhr and Haputstrecke München Augsburg S-Bahn services.
We really need the Berlin S-bahn (or the Hamburg one, but Berlin isn't featured in TSW yet) to get some variety in game!
