Sydbanen
Sydbanen is a government-owned railway in Denmark. Formally it connects Ringsted with Nykøbing Falster, from which it branches to Gedser and Rødbyhavn. Ringsted however is not the terminal station, and so the line is often said to continue to Copenhagen.
The railway is part of the Vogelfluglinie from Copenhagen to Hamburg. On Sydbanen's southwestern end at Rødby, a Scandlines ferry line exists to the German coastal town of Puttgarden, from where the Lübeck–Puttgarden railway and Lübeck–Hamburg railway lead to Hamburg. The Fehmarn Belt Tunnel, to be completed in 2028, will replace the ferry service.
The line is being upgraded to ERTMS from Ringsted to Nykøbing Falster. Furthermore, 55 km of new tracks are being laid, to smooth out curves, allowing for 200 km/h when done. These works are expected to finish in 2021. Afterwards, the line will be electrified. This is slated for completion in 2024.
