Virgin Trains said Network Rail, the owner and operator of Britain's rail system, gave the green light for Virgin to resume services Friday to and from Rugby on the West Coast Main Line. Since December 24, the line (Britain's busiest long-distance rail line) has been subject to delays and service disruptions caused by construction, affecting travel for thousands of passengers. Virgin Trains is offering "Saver" fares on all trains, including peak services, for tickets sold tomorrow, as well as on Monday, January 7 and Tuesday, January 8. Customers holding tickets dated December 31, January 1, 2 or 3 who decided not to travel are eligible for a full refund. Alternatively, those customers can use the tickets on Virgin services through January 8. Visit www.virgintrains.com. (JM)
