I came across some old photos in a cupboard (genuine colour images dating from 1988) of the structures in place after the Wraysbury railway bridge collapse. The bridge failed because contractors took insufficient care of the local land drainage infrastructure.
The first image below shows the nearby iron bridge (similar and constructed about 1850) that was unaffected by the events of 1988.

The image below shows the new railway bridge constructed from adjacent concrete boxes

The image below records that pumping is still required to reduce the groundwater levels.

The image below shows the first stop-log construction after the collapse that was used ultimately to control the ordinary watercourse level.
