Suosituksen perustelu
In 1998 the Accident Investigation Board issued a recommendation The visibility of the stop block should be improved (S72). This recommendation was registered as having been implemented in 2004. A stop block constitutes a safety-critical factor and its visibility should be good. During the investigation, it was discovered that some stop blocks are in poor condition with respect to their visibility. The shape of the stop block does not improve its visibility from the direction of the track. Improved reflectivity could improve the visibility of stop blocks in dark conditions.
Recommendation
Stop blocks should be painted well to ensure their visibility, and the block’s visibility improved by other means.
