Commuters on Merseyrail are to be offered ice-lollies and chilled water by way of apology for disruption attributed to the heatwave.
Trains in the Liverpool area are among many to have suffered cancellations and disruption as a result of buckled rails, as well as the deployment of many trains to operate a shuttle between Central and Liverpool South Parkway while Lime Street station is being refurbished.
Merseyrail's managing director, Andy Heath, said: “We are doing everything we can to keep services running.
“My team will be handing out free lolly ices and water between Kirkdale station and Ormskirk and Kirkby stations this evening as a gesture of apology to our passengers.”
A week ago Network Rail imposed speed limits on some lines because of fears of the continuous welded rails buckling. While the maximum heat in the shade is around 30C, a combination of sunlight and energy generated by trains means the steel rails can reach temperatures approaching 50C.
The rail infrastructure is designed with a wide tolerance to changes in temperature, maintaining the correct track tension during a long and intense heatwave is difficult.
The speed limits have been imposed as a precaution against derailment .
