High-speed rail in Switzerland
, 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
Many of the newly built railway lines in Sweden are adapted for speeds up to 250 km/h, such as Botniabanan, Grödingebanan, Mälarbanan, Svealandsbanan, Västkustbanan, and Vänernbanan.
The problem that is slowing down high-speed rail in Sweden is the present signaling system (ATC), which does not allow speeds over 200 km/h. It can be upgraded, but it will not be done since it shall be replaced by the European signaling system ERTMS level 2 on major lines in the near future, allowing high speeds up to 250 km/h. ERTMS level 2 has been installed and is being tried out on Botniabanan, and that railway allows 250 km/h, although no passenger train goes above 200 for now. The train set X55-Regina has been delivered to the rail company SJ with the max speed of 200 km/h but with the option to upgrade the EMU to 250 km/h when possible. Also the mix with freight trains slow down the practical speed.
