1 source assessed · methodology
Network Rail and British Transport Police data released by BBC London show that trespass on South Western Railway (SWR) tracks caused 9,437 minutes of delay during the 2025/26 financial year. That amount translates to roughly six and a half days when summed across all services. The figure represents the largest single cause of disruption on the network, ahead of cable theft and other forms of obstruction.
Scale of delays
South Western Railway services to be disrupted this weekend
Engineering works around Staines and Teddington will affect services from London Waterloo on Saturday 3 and Sunday 4 October 2026.
Across England, the same period saw more than 3,300 hours of railway delay linked to trespass, cable theft and obstruction, according to the BBC report. Within Network Rail’s fourteen routes, SWR recorded the third‑highest rate of vandalism and obstruction. The incidents include deliberately placed debris and objects on the track, which force trains to stop or run at reduced speed.
Risk of third‑rail system
SWR operates a third‑rail electrification system that delivers 750 volts of direct current. BBC London notes that contact with the rail can cause life‑changing injuries or death. The combination of a high‑voltage supply and unauthorised access raises safety concerns for both passengers and staff.
London Waterloo services face weekend diversions and line closures
South Western Railway will reroute Reading trains and shut the Teddington‑Shepperton line on 3‑4 October, with buses covering affected sections.
Technology response
In response, SWR and Network Rail have launched a campaign that introduces drones, sensors and smart CCTV to improve detection and deterrence of trespassers. The BBC article says the drone trial at London Waterloo station proved successful, prompting plans to deploy additional units at Clapham Junction, New Malden and Walton‑on‑Thames. The technology aims to spot unauthorised individuals more quickly and alert security teams before a train is affected.
Trespass is one of the leading causes of disruption on our network, delaying our customers' journeys and costing taxpayers.
Tom Desmond, operations director, South Western Railway
Tom Desmond, operations director for SWR, told the BBC that the new measures are part of a broader plan to deliver more reliable journeys. He added that the partnership with Network Rail will focus on reducing incidents and improving response times.
The rollout of drones and enhanced CCTV will be overseen by Network Rail’s safety division, which will coordinate with local police. Residents and commuters can expect increased patrols around the identified stations and a visible presence of aerial units during peak periods.
The BBC report does not give a timeline for full deployment, but the trial at Waterloo suggests that additional units could be operational within the next few months. Commuters are advised to stay clear of the third‑rail and report any suspicious activity to British Transport Police.
