UK MPs vote down plan to force GBR into rolling rail electrification

UK parliament has rejected a proposed amendment to the Railways Bill that would have required Great British Railways (GBR) to commit to a rolling programme of rail electrification, with the government arguing it was “not the right way” to set electrification policy. That has reignited criticism of the UK’s stop–start approach to decarbonising its rail network.

The amendment, debated during the Bill’s committee stage in the House of Commons, would have obliged GBR to publish and adhere to a multi-year electrification programme aimed explicitly at lowering delivery costs and improving infrastructure construction performance. It also proposed a defined planning horizon of five financial years, beginning the year after publication.

Supporters in the Commons had framed the proposal as an attempt to hard-wire long-term delivery discipline into the structure of GBR, as the new state-backed rail company prepares to take responsibility for both infrastructure and train operations. The committee, however, voted the amendment down, with the Department for Transport minister Keir Mather saying that “a legislative duty” to upgrade the UK’s tracks was “not the right way” to set electrification policy.

Slipping since the 80s

The decision lands against an increasingly uncomfortable reality, with Network Rail’s recent delivery record becoming emblematic of the country’s wider electrification malaise. In 2022, just 2.2 km of track open for traffic was electrified across Great Britain, a figure widely cited by the industry as incompatible with the ambition of a net-zero railway by 2050.

At the time, former Network Rail chief executive Andrew Haines acknowledged that electrification was slipping politically. In 2023, he said the policy had “dropped down the priority list”, partly because its impact on the UK’s overall carbon budget was seen as marginal compared with other measures. However, the UK’s electrification rollout has been very much stop–start since the 1980s compared with other European nations, which proponents argue is why a rolling, long-term programme should be locked in.

Speaking during Commons debate, Liberal Democrat MP Olly Glover said EU states were “embarrassing” Britain through the scale and consistency of their electrification programmes, arguing that England and Wales had “lost our way” compared with peer nations.

Electrification highs and lows

That comparison is increasingly hard to dismiss. While the UK has struggled to maintain continuity, recent delivery on the Transpennine Route Upgrade (TRU) shows what a corridor-based, phased approach can achieve when funding and scope are sustained. Electric services are now running between Church Fenton and York, marking around a quarter of the Manchester–York route electrified, with further stages planned through to the end of the decade.

Indeed, the TRU model has been compared to practices seen on major European corridors, where electrification is delivered incrementally but predictably, allowing operators to extract immediate benefits from partial wiring. On the Transpennine route, this has already meant more effective use of bi-mode fleets and reduced diesel running under the wires, even ahead of full completion. The point, supporters of the Commons amendment argue, is not that electrification must be instantaneous, but that it must be continuous.

The contrast with the Midland Main Line is stark. Electrification north of Wigston towards Sheffield has been paused indefinitely, with the Transport Secretary saying further work was “not affordable right now”, leaving Sheffield as the UK’s largest city without mainline electrification. Campaigners argue each stop–start pause erodes capability as skills and supply chains dissipate, pushing costs up when work resumes. The Campaign to Electrify Britain’s Railways called the decision “the wrong call for the country”, citing hundreds of millions in lost economic benefit. For now, Sheffield’s stalled upgrade is arguably a more representative snapshot of the UK’s electrification trajectory than the progress on TRU.

So what instead?

As for baking electrification into GBR’s mandate, the DfT’s Keir Mather argued last week that the government’s route is to steer electrification through a forthcoming policy document rather than a statutory duty. He said the DfT is “currently developing a long-term strategy for rolling stock and associated infrastructure”, due to be published in the summer, which “will consider the future approach to electrification.” He added that “electrification may not always be the right solution,” pointing to “trains powered by batteries” and the uncertainty over how technology will evolve over the next “20 or 30 years.”

However, leaving expensive, long-horizon electrification to shifting policy priorities and evolving technology choices, rather than committing to a stable pipeline, is arguably how the UK has ended up with decades of stop–start delivery. For now, “the right way” to electrify the UK’s railways remains familiarly undefined — and uncommitted.
