On Monday last week, the leader of the Malahide Sea Scouts contacted the company with concerns about erosion to the piers.

The following day an engineer inspected the viaduct and found “no visible structural issues, and that all markings were cosmetic”, the company said yesterday.

Two days later, a track monitoring vehicle travelled over the line. This records all dimensions of track, including levels and gauge, and would identify any deviations from normal conditions including those not visible to the naked eye.

It found the railway was operating as designed.

Yet the following day the viaduct collapsed at 6.30pm, moments after a train passed over it.
