Heritage railway bridge collapse: RAIB safety lessons for project engineers
Reviewed by Joe Ashwell
First reported on New Civil Engineer
30 Second Briefing
A 19th‑century heritage footbridge in Gloucestershire collapsed when an excavator, incorrectly loaded onto a works train, struck the structure on the Gloucestershire Warwickshire Steam Railway. RAIB found the plant had been positioned too high on a flat wagon by a volunteer with limited competence and no formal loading plan, breaching the line’s own loading rules. The report presses heritage and volunteer‑run railways to adopt formal competence management, documented loading procedures and clearer structural clearance checks for overbridges and footbridges.
Technical Brief
- For similar volunteer-run infrastructure, findings point to adopting mainline-style safety management systems scaled to local risk.
Our Take
Heritage structures of 19th-century vintage in the United Kingdom often fall outside modern design codes, so incidents like this tend to trigger reviews of how contemporary standards (e.g. for temporary works and load assessment) are applied to volunteer-run or lightly regulated assets.
Across the 262 Failure- and Safety-tagged pieces in our coverage, RAIB investigations frequently lead to formal recommendations that are later adopted by other heritage and light rail operators, so this case in Gloucestershire is likely to influence procedures well beyond the immediate railway.
For UK infrastructure more broadly, our database shows that volunteer or community-operated assets feature in only a small subset of the 104 Infrastructure stories, suggesting regulators may see this collapse as a test case for tightening competence and supervision requirements on non-mainline structures.
