On the Danish side, many trains continue northwards on the Coast Line to Helsingør.
Plans for connecting Scania and Zealand with a bridge had been raised throughout the entire 20th century, and in 1991 a company was created to start the work.
[2] It has been proposed to complement the Øresund Line with a metro link called the Øresundsmetro.
[citation needed] One of the challenges with the line was the incompatibility between the railway electrification systems in Denmark and Sweden.
The problems were overcome by requiring all trains operating on the line to be dual voltage and have dual signalling systems, including a minority of the X2 trains operated throughout Sweden by SJ.
The entire bridge has 200 km/h (125 mph) maximum speed, also the Danish part, as the only railway in Denmark.
Furthermore, from January 2016, a carrier's responsibility law was in effect, so all passengers had to go through identity check at Copenhagen Airport station, and all passengers from other Danish stations had to disembark, change track and go through the identity check.
