The Met Office has issued red and amber weather warnings for Greater London and Kent through to Thursday 25 June, with temperatures forecast to reach up to 38°C. These conditions are likely to affect rail operations across the network.
While Southeastern plans to operate a full timetable, the extreme heat may require operational adjustments to ensure the safety of passengers and staff. Rail temperatures can reach around 50°C in direct sunlight, which may lead to speed restrictions, longer journey times, and an increased likelihood of delays or short-notice changes to services.
Customers are being advised to travel only if absolutely necessary during the hottest periods, particularly on Wednesday and Thursday when temperatures are expected to peak. If they do need to travel, we encourage them to check their journeys before travelling, allow extra time, and travel at quieter times where possible. They are also advised to stay hydrated and seek assistance from staff if needed.
For those who choose not to travel on Wednesday 24 or Thursday 25 June, tickets can be refunded or used on alternative dates (Tuesday 23 or Friday 26 June) at no extra cost. If the journey includes other train operators, customers should check National Rail Enquiries for the latest information on arrangements for their full journey.
We’ve put extra support in place across the network to minimise disruption and support customers, including:
Additional staff and mobile response teams across the network
Increased traincrew and engineering resource
Preparation of trains to support air conditioning and reduce heat-related faults
Engineering teams positioned at key locations to respond quickly
Enhanced monitoring of track and infrastructure
Additional water supplies available at stations and on trains
Conditions will continue to be monitored closely, and travel advice may change as the week progresses.
