Network Rail has implemented a nationwide prohibition on the operation of steam trains, citing concerns over their potential to ignite wildfires during Britain's ongoing heatwave. The drastic measure follows an incident in Cheshire where a West Coast Railway (WCR) service, popularly known as the 'Harry Potter train' due to its use in the film series, is thought to have sparked a significant blaze. The wildfire led to considerable disruption on the West Coast Main Line, resulting in 72 train cancellations and 158 delays.
The grounding of steam services has caused widespread cancellations and forced operators to deploy diesel engines as last-minute replacements. This decision comes at a particularly inconvenient time, as schools across the country are beginning their summer holidays, meaning many families and enthusiasts will be left disappointed by the inability to experience these historic journeys.
Network Rail is currently investigating the precise cause of the Cheshire fire. However, a spokesperson emphasised the necessity of the ban, stating that prolonged periods of hot, dry weather have significantly heightened the risk of wildfires across the country. The organisation's steam charter fire risk policy dictates that coal-fired engines, which produce burning cinders and sparks, should not be used under certain weather conditions.
While these sparks typically pose minimal threat, three consecutive heatwaves have pushed temperatures as high as 37C in some areas, leaving trackside grass embankments and surrounding farmland exceptionally dry. This parched landscape dramatically increases the likelihood of a stray spark developing into a full-scale fire. Fire and rescue services in England and Wales have already responded to 342 wildfires this year, with 65 covering areas of 30 hectares or more. This week alone has seen 19 separate wildfire incidents, a phenomenon experts have termed a 'firewave'.
The National Fire Chiefs Council (NFCC) has issued a warning that the current heatwave presents extreme risks for further firewaves. They highlighted that sustained warm, dry conditions lead to vegetation drying out, which is expected to increase the risk of larger, faster-moving, and more challenging wildfire incidents in the coming days and weeks. A spokesperson from Mid-Norfolk Railway described the decision to pause steam train operations as 'the responsible course of action' amid the rising reports of wildfires, aligning with the Met Office's recent 'State of the Climate' report, which indicated that extreme weather events are becoming increasingly common in the UK.
