A year after nationalisation, is South Western Railway delivering?

South Western Railway has introduced new Arterio commuter trains in Great British Railways livery. The trains feature air-conditioned carriages, more space, and greater passenger capacity, with 10 coaches instead of eight. The rollout has faced earlier setbacks, including technical problems and delays tied to the previous fragmented private system. After renationalisation, only six new trains were running, but 12 months later half of the new 1bn fleet of 90 trains is in service, with a path toward a majority. Rail minister Peter Hendy attributes progress to reforms, including a single managing director responsible for both track and trains and incentives focused on service quality rather than strict contract compliance.

"South Western Railway's newest train, wrapped in union jack-inspired Great British Railways livery, may divide opinion on aesthetics, but the interior is certainly an upgrade: air-conditioned carriages, more space and greater passenger capacity. For ministers, the fact that it is the 45th Arterio model brought into service since the SWR network was nationalised is vindication of the GBR approach."

"However, exactly 12 months on, SWR has reached the threshold where half and soon a majority of the new 1bn fleet of 90 commuter trains is running after years of delay since the order was placed under the old privatised and fragmented system. Speaking at the launch at London Waterloo, Peter Hendy, the rail minister, said the accelerated rollout since May 2025 showed the difference reforms were already making."

"A single managing director is responsible for both track and train and is incentivised on running a decent service rather than operating to the letter of a contract. Nationalisation was cutting red tape that held the railway back for decades, Lord Hendy said. A variety of technical problems had delayed the introduction of the SWR trains."

"They were ordered in the last decade, with the first models built six years ago, but were largely languishing in the sidings as the last private operator, First Group, grappled with union objections and its contractual demands. Only six were running when the state took direct control. A year on, we've got half these new trains in service, he said. They've got more capacity they're 10 coaches, not eight and they're more reliable. The old ones have gone to a knacker's yard."
