Electrification Industry Warns Skills Drain Could Push Up Rail Costs Without Long-Term Pipeline

Rail industry leaders are warning that the UK's stop-start approach to railway electrification is driving skilled workers out of the sector and making future projects more expensive.

A new report from the Railway Industry Association (RIA) argues that adopting a continuous programme of electrification schemes could significantly reduce costs while providing the confidence needed to retain specialist expertise and attract investment across the supply chain.

The study comes as the rail electrification sector grapples with a sharp contraction in its workforce. Industry figures suggest around 850 jobs have disappeared over the past year alone, including approximately 500 roles linked to the completion of major electrification work on the Midland Main Line.

According to the report, the UK's electrification workforce has fallen dramatically over the past decade. Numbers have dropped from more than 10,000 people in 2018 to around 3,650 today, with a substantial proportion of those remaining employed in maintenance rather than project delivery.

Industry representatives argue that the boom-and-bust cycle of rail investment is one of the main reasons costs remain higher than they need to be. Each time a major scheme finishes, specialist teams are disbanded, equipment is redeployed and supply chains contract, only to be rebuilt again when the next project begins.

The report estimates that a rolling programme of electrification could reduce delivery costs by as much as 30 per cent compared with current project-by-project approaches, largely by avoiding repeated mobilisation and demobilisation expenses.

RIA Senior Technical Adviser David Clarke said the industry has repeatedly suffered from abrupt changes in government investment decisions, making businesses reluctant to expand their capabilities or invest in new technologies.

He argued that a stable pipeline of work would provide the certainty contractors need to retain staff, develop skills and improve productivity over the long term.

The report also calls for the creation of a protected funding framework to provide greater confidence for both government and industry. Under such an approach, projects would be delivered within a defined budget envelope, while any efficiency savings could potentially be reinvested into additional schemes.

Alongside funding reform, the report highlights the need for closer collaboration between the rail and energy sectors. As railway electrification expands and battery-powered trains become more common, demand for electricity infrastructure is expected to grow significantly.

Industry leaders say rail must play a larger role in discussions about future grid capacity, renewable energy integration and long-term power supply planning.

The findings are expected to feed into ongoing government work on the forthcoming Rolling Stock and Infrastructure Strategy, which is intended to set out future priorities for Britain's railway.

Supporters of a rolling electrification programme point to Scotland as an example of how a continuous pipeline of projects can improve efficiency and reduce costs over time.

Campaigners argue the evidence is now clear that sustained investment delivers better value than short-term schemes, but warn that delays in implementing a long-term strategy risk further erosion of skills and expertise across the sector.

With workforce numbers continuing to fall and future projects yet to be confirmed, industry leaders are increasingly concerned that valuable knowledge could be lost before the next major wave of electrification begins.
