Temperatures as high as 33°C (91.4°F) were registered shortly before the crash.The RAIB says the clay embankment and the material underneath it are sensitive to changes in moisture content, and may move as moisture levels change.The continuing investigation will now consider elements including how that section of track was inspected and maintained, the condition and maintenance of the embankment, the weather conditions and how effective any hot weather mitigation measures were.In a joint statement, Lucy McAuliffe, Network Rail's route director for Sussex, and John Whitehurst, chief executive of Greater Thameslink Railway, apologised for the derailment.They added: "We will carefully consider any recommendations arising from the investigation and work across the industry to implement them, with the shared goal of making an already safe railway even safer for our customers, colleagues and the communities we serve."Image caption, A map shows the train's journey from London to Eastbourne, which was due to be its final stopLast Friday, Network Rail's group safety and engineering director Martin Frobisher told the BBC speed restrictions were not in place along the section of track when the derailment happened.He insisted the railway was safe, and that Network Rail took various measures to manage the impact of weather on tracks and other railway equipment.The Department for Transport released a statement saying "safety remains the absolute priority across our rail network".The statement added: "The UK's railways remain among the safest in the world, with the number of delays caused by track faults falling by 45% since the late 2000s."Follow BBC Sussex on Facebook, external, X, external, and on Instagram, external and listen to BBC Radio Sussex on Sounds.
