The reinstatement of double track on the Cotswold Line has been a tremendous success, but unfortunately is not the complete answer to capacity problems, due to the retention of a long single track section from Charlbury to Wolvercote Junction. This became apparent on 19 July 2013, when the 1P57 14:26 Great Malvern to Paddington First Great Western service became delayed at Charlbury, due to the late arrival of the 1W41 14:21 Paddington to Worcester Foregate Street (which in the event terminated at Shrub Hill). Running fifteen minutes late, 180103 leaves Charlbury and joins the single track section, with the delayed 1P57.
