The North West has benefited considerably from the £8.9 million upgrade of the west coast main line. Since December 2008, more and faster trains have run between London and Chester, Liverpool, Manchester, and major towns and cities between Crewe and Glasgow. Northern Rail services were also improved on the route between Bradford and Manchester and the Cumbrian coast line. Investment to improve reliability has resulted in the best levels of performance ever experienced by Northern Rail during the four-week period ending 30 May 2009.
