The long wait once the level crossing is closed is due to a 40 km/h speed restriction 2.7 km before (Km 522.9, the level crossing being at 520.2) :
the train is slowly accelerating from there, because of the 1 in 100 gradient and its heavy load (14 coaches), and hasn't reached
its permitted speed (110 km/h) yet... One may also note the wifi antennas on the roof of most coaches (all were equipped at the end of 2019).

The speed of the train is approximately 40 km/h, and remains stable because of the speed restriction mentioned above : a bit more than
1900 kW at the rail head are needed in order to hold that speed with a load of 1,800 tons in a 1 in 100 gradient, and that comes very close
to this locomotive's maximum capability. So, speed will only increase after the summit, one km further along.

This train begins to move just after a GYSEV IC train bound for Budapest-Keleti has passed. The little music piece
that can be heard at the beginnng is typical of Class 182 DB / 1116 ÖBB Taurus locomotives. One may note how fast the train reaches 60 km/h.
No big surprise though, with a dry rail, a slight descent and 7000 kW avaiable (continuous rating 6400 kW)... even with a BoBo loco's
limited adhesion. Productivity : this train is not very long (552 m), but 100 % loaded.
