Rail services across Essex are delayed after Greater Anglia imposed emergency speed restrictions on 29 July 2026 following forecasts of temperatures reaching 34C, the Met Office confirmed. The UK Health Security Agency issued an amber heat health warning for Essex in conjunction with the extreme heat conditions.
Speed Restrictions Between Ingatestone and Chelmsford
Emergency speed restrictions are currently active on all lines between Ingatestone and Chelmsford stations. These measures slow train operations to protect rail infrastructure at risk from heat-related damage. Disruptions are ongoing with no specified end time.
Passenger Guidance and Compensation
Passengers holding advance tickets affected by cancellations may travel on earlier or later services without additional charge.
Those experiencing delays of 15 minutes or more are eligible to claim compensation on their fares, according to Greater Anglia’s policy.
Apologies and Updates
Both Greater Anglia and Network Rail issued apologies for the delays impacting Essex rail services. Greater Anglia stated an update regarding the situation would be provided within an hour of 11:55 GMT, the time this information was released.
Heat Impact on Rail Infrastructure
The heatwave has elevated the risk of track damage, prompting speed limitations as a safety precaution on affected lines. The UKHSA’s amber warning highlights additional health risks posed by the unusually high temperatures in the region.
