Accident
3.1.2019
2019-S4
Suosituksen perustelu
The railway operator’s guidelines on the number of stop blocks failed to take account of the weight of the wagons or the longitudinal gradient of the track. The guidelines overestimated the holding power of the stop blocks. Guidelines on ensuring that wagons remain stationary should be drawn up by the infrastructure manager in order to ensure their consistency in a multi-actor environment.
Recommendation
The Finnish Transport Infrastructure Agency will draw up guidelines on keeping wagons stationary in the Finnish state rail network.
Suosituksen tarkennus
The number of stop blocks must take account of the longitudinal gradient of the track, the weight of the wagons and the true holding power of the stop blocks.
