Punktförmige Zugbeeinflussung
After acknowledging the warning signal the train has to stay below the braking curve (German "Bremskurve") - fast trains may travel up to 165 km/h and they must reduce the speed to below 85 km/h after 23 seconds. Note that the operation of high speed trains beyond 165 km/h is not based on visual wayside signals or PZB inductors (using LZB or European Train Control System cab-signalling instead in Germany).
High-speed rail in Europe
There are investigations regarding high-speed trains in Sweden, and to evaluate if the Western and Southern Mainline should be upgraded to 250 km/h or if a whole new network of high-speed railway for should be built between Stockholm–Linköping–Jönköping–Gothenburg and between Jönköping–Malmö–Copenhagen. The plan is to ease the situation on the existing railways that are relatively congested, combined with better travel times between both the largest three cities in Sweden, as well as fast regional trains between the cities along the routes (which today in many cases have no or slow railways).
