Rail geometry measurements during track construction

The rail inconsistency that was uncovered during the investigation would have been noticed earlier if track geometry measurements had been completed before the rail was taken into use, for example during final rail securing work. Final rail securing work is a good time for this, since today’s securing machines enable track geometry measurements. Measurements could be a quality requirement. This would ensure that any geometries that do not meet regulations would become apparent before track commissioning.

Demanding surface construction projects should include rail geometry measurements before the track is taken into use. The measurements could be compared with set limit values.
