UK weather: Heatwave causes railway slowdown and wildfires, and it will get even hotter until weekend

As scorching temperatures are set to last until the weekend, Network Rail has deployed “extreme weather action teams” in readiness for even warmer conditions following a peak of 30.1C (86.1F) on Monday, which was the hottest day of the year so far. The announcement came as wildfires took hold in parts of northern England and the Met Office issued its first “yellow” health warning for heatwave conditions of 2018 from Tuesday until Thursday evening.
