What happened

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.

Lessons learned

  1. A substation fire next to a railway can close the line for hours, so operators must map transport corridors and plan service alternatives in advance.
  2. Enclosed substations need pre-agreed smoke ventilation methods with fire services to speed clearance and reduce disruption.
  3. Joint plans with rail operators for electrical fires must cover isolation, access and service restart criteria.
