The Department for Transport must continue identifying lessons from other major rail projects, such as Crossrail and HS2, to avoid similar failings, according to the National Audit Office.

HS2 engineers have launched a 130m-long steel bridge over the Grand Union Canal, allowing a 1.5-mile section of the canal to be reopened to the public seven days ahead of schedule.

Engineers working on HS2’s triangular intersection outside Birmingham have completed the construction of four parallel viaduct decks.

Chancellor Rachel Reeves has backed Northern Powerhouse Rail (NPR), after more than a decade of uncertainty over the project’s future.

A £5.9 million railway bridge has been driven into position by Network Rail engineers at a site in West Dunbartonshire, Scotland.

BAM Nutall has been appointed as the design and build contractor for the upgrade of Cardiff Central railway station.

Balfour Beatty has completed a trial of Engine Carbon Clean (ECC) technology as part of its mission to reduce emissions across its rail operations.

The Construction Plant-hire Association (CPA) has released new guidance for cranes operating near live rail environments.

HS2’s tunnel excavation between London’s Old Oak Common and the West Midlands has been completed, marking a significant milestone for the project.

A train derailment in Surrey last year was caused by maintenance workers leaving a redundant rail across the tracks.

Network Rail has been fined £3.75m and ordered to pay costs of £175,000 after the deaths of two track workers in 2019.

Despite progress in the safety of track maintenance works in British railways, near-miss incidents in 2022 suggest that “considerable risk still exists” for staff working on the railways.

The construction industry has reacted with dismay to the government’s announcement that the Birmingham to Crewe leg of HS2 will be delayed by two years due to rising costs.

Two 2,000t tunnelling machines digging the HS2 tunnel under the Chilterns have completed the first stage of works.

HS2 has unveiled an updated design for its new high-speed rail terminus in London.
