Ringbanen

Ringbanen () is an S-train line in Copenhagen. Its route is roughly semicircular, running around the central part of Copenhagen and connecting the S-train radials about 5 km out.

==History== The ring line started as a freight bypass railway. In 1900 Copenhagen had a central station situated just inside Skt Jørgens Sø, from which railways went towards Roskilde (via ) and (via Nørrebro, not the current station but where Nørrebroparken is now). A connecting line directly from Nørrebro to Frederiksberg was used by transiting freight, in order to relieve the central station which had been pushing its capacity limit for decades. Apart from capacity problem, the lines through Frederiksberg and Nørrebro had many level crossings, to the increasing irritation of motorists as their number and the number and trains both grew.
