Train passengers have faced chaos today as a power cut and problems with overhead wires caused long delays.
Leeds station was plunged into darkness shortly before 9am due to a power cut, which left shops unable to open and staff having to use torches.
And trains between London Kings Cross and Doncaster were delayed by 90 minutes because of overhead wire problems.
Amid the chaos, members of the Rail, Maritime and Transport (RMT) union at London Midland were balloting for strikes over the sacking of a colleague.
The union claimed its member James Crabtree, who worked as a revenue protection officer, was sacked for resisting an assault by a known troublemaker.
Network Rail said some East Coast services were still delayed by up to 30 minutes because of this morning’s problems.
