The operator has a large red warning box on its website.
EMR says:
‘Now summer is here and temperatures are due to soar this weekend, journeys by rail can sometimes be affected. Railways are particularly susceptible to changes in temperature, with hot weather able to cause rails to expand, bend or buckle.
‘Network Rail will be monitoring track temperatures to understand when rails may be at risk of damage which could directly impact the trains. In addition, Network Rail sends out engineers ahead of time to check track condition and carry out any proactive work to minimise disruption.
‘EMR work closely with Network Rail to ensure the railway runs safely.
‘For some of us, hot weather is a dream come true, for others, it’s a hot mess. We want you to be comfortable when travelling on our services and that’s why most of our trains have air conditioning.’
