    Heritage railway bridge collapse: RAIB safety lessons for project engineers

    Heritage railway bridge collapse: RAIB safety lessons for project engineers

    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.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
