The Oswestry, Ellesmere and Whitchurch Railway was a railway company that constructed a line from Whitchurch via Ellesmere to Oswestry. Most of the line was in Shropshire but part entered Flintshire, now Wrexham County Borough. It was seen as a link from the local railways around Newtown to the London and North Western Railway, breaking the local monopoly of the Great Western Railway. It opened as a single line in 1863 and 1864. Throughout the construction period it was short of money, and was paid for by the contractor, who took shares. Sporadically through its life it became a useful part of a through route for mineral trains, but it never developed greatly.
