Fire at New Milton substation causes major rail service disruption

In 2026, a fire broke out at New Milton substation, adjacent to a railway line in New Milton, Hampshire, United Kingdom. Emergency services were called after reports of smoke shortly after 06:30 local time. Fire crews used ventilation fans to clear smoke from the site and stood down later that morning. A section of rail line was closed for several hours, with services resuming that evening. Multiple long distance and regional rail operators were affected, with delays reported of up to 45 minutes, cancellations and revised timetables across a wide area for the remainder of the day. No injuries were reported in connection with the fire.

1. Identify substations sited next to railways, roads or other critical transport corridors and assess in advance the wider disruption a fault or fire at each site could cause.
2. Agree smoke clearance and ventilation arrangements with the local fire and rescue service in advance for enclosed or confined substation buildings, so that equipment and access routes are known before an incident.
3. Put joint contingency and communication plans in place with the operator of the adjacent infrastructure, covering isolation, safe access and the criteria for resuming services after an electrical fire.
4. Plan for outages lasting a full operating day rather than a few hours, including passenger or customer information and alternative arrangements.
