High-speed rail in Europe
Switzerland has no high-speed trains of its own yet. French TGV (TGV Lyria) and German ICE lines extend into Switzerland, but given the dense rail traffic, short distances between Swiss cities (because of the country's small size) and the often difficult terrain, they do not attain speeds higher than 200 km/h (ICE3) or 160 km/h (TGV, ICE1, ICE2). The fastest Swiss trains are the ICN tilting trains, operated by the Swiss Federal Railways since May 2000. They can reach higher speeds than conventional trains on the curve-intensive Swiss network, however the top speed of 200 km/h can only be reached on high-speed lines. The former Cisalpino consortium owned by the Swiss Federal Railways and Trenitalia used Pendolino tilting trains on two of its international lines. These trains are now operated by the Swiss Federal Railways and Trenitalia.
High-speed rail in Europe
Construction of a new 60 km Copenhagen–Ringsted Line, which will allow speeds up to 250 km/h began in 2012. Furthermore, the railway line towards the future Fehmarn Belt Fixed Link was upgraded to 160 km/h in 2010, and will be upgraded to a 200 km/h doubletracked line in 2021. Once these two projects are finished Denmark will be able to link the Swedish high-speed lines with the rest of the European high-speed rail network - assuming that Germany builds a high-speed link between Hamburg and Fehmarn (their plan is to stay at 160 km/h for cost reasons)
