During Monday to Saturday daytimes, this is the regular service pattern, however due to the Preston to Manchester electrification works during the 2015 summer timetable, there was an amended timetable throughout this period. There were no train services between Bolton and any Manchester station on Saturdays and Sundays between 2 May to 13 December, trains were routed via Walkden.
