Not to be implemented
Rail R
Accident
30.1.2012
C1/2011R/S306
Suosituksen perustelu
In the MiSO TCS system, the axle counting system emergency release function for line sections with low traffic volumes has been set to release the section without special conditions. In some parts of the railway network, the axle counting emergency release function must detect at least one axle leaving the section. Emergency release of the axle counting system is possible only after this has occurred. The purpose of this is to ensure that the last event was a unit leaving the section.
Recommendation
It should be a prerequisite for the emergency release of all axle counting sections, that the last axles counted at an axle counting point must be axles exiting the section.
