Llangollen Canal part of the London Midland and Scottish Railway soon afterwards. After the takeover by the London Midland and Scottish Railway, regular maintenance was often not carried out, and gradually the canals silted up, so that boats could not operate with full loads. Traffic declined, and was significantly affected by a breach that occurred at the Perry Aqueduct, about to the south of Frankton locks, which effectively closed the Montgomeryshire Canal to all traffic. Traffic beyond Frankton to Llangollen had ceased in 1937, and the Frankton to Hurleston section was not used after 1939. The London Midland and Scottish Railway obtained
Llangollen Canal canal by another , and by the upper lock is the grade II listed Swanley Hall, a red-brick farmhouse parts of which date from the early 16th century. Baddiley Hall, which has three storeys and an attic, and dates from the late 17th century, is set some distance back from the canal. In its grounds is the grade I listed parish church of St. Michael, the chancel of which dates from 1308, while the nave dates from 1811. Both are separated from the canal by a scheduled monument site, containing the earthworks and buried remains of an abandoned medieval village.
