Train operators in England and Wales are urging passengers to only travel if they must, as the heatwave continues. Red and amber warnings of extreme heat are still in force, particularly in south east England, and there is also a risk of thunderstorms.

The train from Corby which ran into the back of a stationary train south of Bedford, killing the driver and injuring more than 160 passengers, had passed a red signal a few moments before. The RAIB has issued its first report into the collision on 19 June, also revealing that the Corby train was travelling at almost 50mph.
