Train routes across Merseyside have been cancelled due to the UK’s current heatwave.
Merseyrail are advising people not to travel on its services with temperatures in the region expected to hit 34°C for a second day running on Tuesday.
The transport operator said services will face significant disruption due to the searing heat already causing problems to Network Rail’s track and equipment.
Services on the West Kirby and New Brighton lines will only run between Birkenhead North and Liverpool city centre at a 15-minute frequency.
Chester and Ellesmere Port services will also run every quarter of an hour on a reduced service between Rock Ferry and Liverpool city centre.
Trains between Southport and Hunts Cross will have a limited service at Bank Hall, Hightown, Hall Road and Hillside and running at 30-minute intervals.
The Hunts Cross line will start and terminate at Liverpool South Parkway with rail replacement buses continuing to run between the two local stations.
Normal service will operate on the Ormskirk line but the Kirkby line will have no trains or rail replacement buses running until the end of Tuesday, July 19.
Anyone still travelling on the network is advised to take a soft drink or water while Merseyrail staff will be on hand to help passengers struggling with the heat.
Passengers who feel unwell while on a train should depart at the next available stop and request help from the station staff.
Zoe Hands, Merseyrail’s chief operating officer said: “We apologise to Merseyrail passengers for the reduction of some services, this is due to a number of heat related issues with the infrastructure which mean our trains are unable to operate as normal.
“If you do have to travel, please remember to take water with you and to leave more time for your journey as disruption is possible.
“We are confident that services will return to normal from Wednesday onwards”
Kara Wood, Head of Performance and Customer at Network Rail’s North West route, added: “The predicted high temperatures could cause track temperatures to reach more than 50°C.
“When steel becomes very hot, it expands and rails can bend, flex and, in serious cases, buckle. These could lead to some trains being delayed, cancelled or stranded.
“In this extraordinary heat, rail passengers are being asked to only travel if absolutely necessary.”
