National Express is launching a special offer in February. The operator is selling thousands of one way seats for £5. The fares are launched as engineering works on the West Coast Main Line are poised to cause significant disruption for travellers to and from London on a number of dates this February. They will see train travellers facing up to three changes, with some journeys extended by almost three hours. The online Funfares are part of the company’s efforts to attract people off trains and onto coaches during the rail disruption.
