    VolkerRail Croydon tram loop renewals: slab track lessons for engineers

    VolkerRail Croydon tram loop renewals: slab track lessons for engineers

    First reported on New Civil Engineer

    30 Second Briefing

    VolkerRail has completed a month-long programme to renew more than 750m of embedded track on the Croydon central tram loop on the London Trams network. Works focused on replacing street-running rail sections set in concrete, requiring staged possessions and traffic management through Croydon town centre to maintain tram and road access. The scheme will be relevant for engineers dealing with embedded grooved rail, slab track detailing, and managing construction interfaces with urban utilities and streetscape.

    Technical Brief

    • Embedded track form involves grooved rail cast into concrete slab within existing street carriageway.
    • Similar embedded grooved-rail renewals in UK tramways often adopt comparable slab replacement and staging strategies.

    Our Take

    VolkerRail’s month-long Croydon tram works sit alongside its recent 22‑day blockade into central London and the Sheffield Supertram ‘Delta Junction’ renewal, signalling a deliberate push into complex, time‑compressed urban track possessions in the UK.

    Handling more than 750 m of embedded track renewal on a tram loop reinforces VolkerRail’s credentials for street‑running rail systems, which is likely to be relevant as UK cities revisit light rail and tram‑train options within the 905 Infrastructure stories tracked in our database.

    VolkerRail’s role here complements its appointment to the Midlands Rail Hub Alliance, suggesting London Trams and other urban operators are drawing on contractors already embedded in major Network Rail upgrade programmes for critical renewal work.

    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.
