high-speed line in Russia with trains operating at up to 350 km/h, reducing travel time from 13-hour to 3.5 hours. In comparison, trains on the Moscow–St. Petersburg line run at up to 250 km/h. In 2019, the date of opening changed to 2024, the initial track length was shortened from 770 km to 301 km. Sweden Many of the newly built railway lines in Sweden are adapted for speeds up to 250 km/h as Botniabanan, Grödingebanan, Mälarbanan, Svealandsbanan, Västkustbanan, Vänernbanan (Gothenburg – Trollhättan). 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. There are four major high-speed projects proposed in Sweden with speeds between 250 and 350 km/h. Norrbotniabanan, Umeå – Luleå, is a future major rail project that will be built for 250 km/h with mixed passenger and freight traffic in northern Sweden, mainly to relieve the highly congested and old single track Main Line Through Upper Norrland increase freight traffic, and greatly speed up passenger traffic along the coast. Ostlänken: Järna – Linköping, which would relieve the congested and slow conventional main lines on the stretch Järna-Linköping, Södra stambanan. Götalandsbanan: Gothenburg – Jönköping – Linköping on to Stockholm via Ostlänken. It would reduce travel time Gothenburg-Stockholm from 3.05 h to 2h. Europabanan: Jönköping – Lund. Possibly extended to Helsingborg, Helsingör (Tunnel under Øresund) and Copenhagen. The three first listed, but not Europabanan, have been prospected in detail by Trafikverket. In several cases the detailed alignment has been decided. There is a political interest to build all these four. The Swedish Moderate government decided in 2012 to build Ostlänken, but with mostly max 250 km/h, after putting all projects on hold in the budget of 2011.
