Network Rail is urging passengers to check their journeys are still running as the heat takes trains off tracks.
As previously reported, the temperatures soared over 35 degrees celsius on Thursday, July 26 and commuters are feeling the aftermath today.
The country’s rail network is made up of 20,000 miles of steel track, which absorbs heat easily and could buckle under the pressure
All trains have been slowed while running over the hot rails, to reduce the chances of buckling.
East Midlands Trains are running a reduced service for another day, potentially bringing widespread disruption and crammed carriages.
Passengers are strongly advised to consider alternative travel arrangements and only travel if their journey is absolutely necessary.
