Rail passengers are experiencing slow-moving trains due to the arrival of Storm Doris.
High winds of up to 80mph are sweeping across Northern England and Scotland.
Network Rail has put in place a temporary speed restriction on the West Coast Main Line between London Euston and Preston.
Chief operating officer for Network Rail’s London North Western route Mark Killick said: “In light of the anticipated poor weather caused by Storm Doris, temporary 50mph speed restrictions will be imposed tomorrow across sections of the West Coast route, the Chiltern line and the West Midlands.
“This may lead to delays on some services. The purpose of these speed limits is safety. Keeping passengers and railway staff safe is, as always, our top priority.
“Weather conditions will be continually monitored and if they change we will reevaluate our response.
“We’re deploying extra Network Rail staff to deal with any issues such as fallen trees, and overhead line issues with the aim of keeping people on the move.”
