English: Winter days on the Canal near to Garth, Wrexham/Wrecsam, Wales. The Llangollen Branch of the Shropshire Union Canal at Trevor had a sad history of bank slips and leaks. The most severe incident occurred in this area when the burst bank and associated debris slipped onto the railway line below causing a train to be derailed leading to the death of the locomotive crew. The modern canal engineer has got over these problems by bolting a concrete trough to the hillside to prevent this movement. I'm sure Thomas Telford would have used this technique if it had been available to him 210 years ago. In the distance is a view of Castell Dinas Bran above Llangollen.
