The train quality class is 3, 80 120 km/h, the maximum axle load is 32 t, and the annual accumulated tonnage is over 22 MGT.
The most relevant parameters of geometry of tracks are the distance between their centers, gauge, the maximum axle load, gradient, the minimum horizontal and vertical radius of curvature, the maximum cant and the maximum cant gradient, and the length of transition curves corresponding to the minimum curve radius.
This gives a maximum axle load of 12.5 t.
The upgrades allowed the maximum axle load to be increased to 22 t and the train weight to increased to 1800 t.
However, the Norwegian variation was scaled down due to the maximum axle load (16.0 t, Class 120 has 21.0 t) and had a lower power output than the Class 120.
The maximum axle load was increased from 18 t to 22.5 t, equivalent to the standard on the Swedish side, and the maximum speed for freight trains increased from 50-80 km/h for freight trains, and from 100-130 km/h for passenger trains.
The tyre loading was for a maximum European axle loading and then greater and lower than this value.
The line was 27.45 km long, had a maximum gradient of 4.5 percent, a minimum curve radius of 180 m, a maximum speed of, a maximum permitted axle load of 12 t, standard gauge and a electrification system.
If it exceeds the maximum rated axle load, it will cause more damage to the track so, for infrastructure managers, a lower or safer axle load limit is desirable.
Axle load is therefore an important design factor in the engineering of railways, designed to tolerate a maximum weight‐per‐axle (axle load).
