One year on, South Western Railway still faces reliability questions despite progress under public ownership

Twelve months after becoming the first train operator to return to public ownership under the Government’s rail reform programme, South Western Railway (SWR) is pointing to progress on fleet modernisation and service improvements.

However, questions remain over reliability and whether nationalisation has yet delivered the benefits promised to passengers.

At the centre of the operator’s recovery effort is the introduction of the new £1 billion Arterio fleet. More than 40 of the 90 trains are now in service, marking a significant acceleration compared with the years of delays experienced before SWR was brought under public control.

The modern trains offer air conditioning, increased capacity and improved accessibility, replacing ageing commuter stock that had served passengers for decades.

Rail Minister Lord Peter Hendy has cited the rollout as evidence that Great British Railways-style reforms are already beginning to deliver results.

Speaking at London Waterloo, he argued that bringing track and train management closer together had helped remove barriers that previously slowed decision-making and delayed investment.

Before nationalisation, only a handful of Arterio units had entered passenger service despite the trains being ordered years earlier. Today, around half of the fleet is operational, with more expected to enter service over the coming months.

However, while ministers highlight the fleet programme as a success, passengers continue to experience reliability challenges across the network.

SWR's performance has been affected by a combination of infrastructure failures, staffing shortages and operational disruption, leading to criticism that public ownership has yet to translate into consistently better journeys.

Lord Hendy acknowledged that improvements are still needed, arguing that the operator inherited a number of long-standing issues.

He said:

“A year on, we’ve got half these new trains in service. They’ve got more capacity – they’re 10 coaches, not eight – and they’re more reliable.”

He also suggested that staffing arrangements inherited from the previous franchise model had contributed to operational difficulties, claiming that complex rostering arrangements made the railway more vulnerable when disruption occurred.

According to Hendy, rebuilding reliability will require additional driver recruitment, timetable changes and continued infrastructure improvements.

SWR and Network Rail Wessex are now led by a single managing director, Lawrence Bowman, in a structure that ministers say reflects the future direction of Great British Railways by bringing track and train operations under closer management.

Bowman said the business is making progress but acknowledged there is still considerable work ahead.

“We have a lot more to do, but we are making steady progress towards building a more reliable and resilient railway for the future,” he said.

The anniversary also comes amid wider debate about the future identity of Britain's railways. While South Western Railway now operates under public ownership, its existing brand remains in place alongside the emerging Great British Railways identity.

Meanwhile, the introduction of a new red, white and blue GBR-inspired livery has attracted mixed reactions, generating discussion across the rail industry and among passengers.

For ministers, however, the key measure of success remains performance rather than branding. While the rollout of the Arterio fleet represents a tangible achievement, the coming months are likely to determine whether improvements in reliability and customer experience can keep pace with the ambitions set out under rail reform.

One year after nationalisation, the verdict remains mixed: progress has undoubtedly been made, but for many passengers, the true test will be whether the railway becomes more dependable day-to-day rather than simply operating under a different ownership model.
