UK heatwave causing delays on railways!

Commuters have been facing travel scares this week as railway operators warn people of delays due to temperatures rising to 30 degrees! Perfect timing before the major railway strikes towards the end of June. At this point you might be wondering, why would a little hot weather cause railway delays? Surely that can’t be, right? However, you’ll be surprised to find out that this problem can be a nightmare for railway workers across the UK. Keep reading to find out more about why high temperatures can cause quite a major backlash on train times. However, before we do this, let’s talk about what the Chiltern railway spokesmen had to say about the matter.

“Due to expected hot weather, speed restrictions will be imposed on the rail from today until Saturday 18th of June” additionally, the spokesman warned commuters to, “expect delays”, and to ensure you, “check your journeys before you travel”.

Now for those who are intrigued as to why trains are usually delayed when there’s hot weather, let us tell you why. It’s because all of the train drivers decide to have a day out at the beach! Haha, We nearly had you there! The real reason why this happens is due to steel rails being exposed to hot weather, which can sometimes cause the material to become 20 degrees hotter than the air temperature. Furthermore, according to Network Rail, the resulting temperature increase can cause extreme compression and buckle on the rail lines, and when this happens it can lead to that area becoming unsafe to travel over. Therefore speed restrictions are put in place when travelling past the affected railway lines. This is because slower trains exert lower forces on the track, reducing the risk of the train buckling.
