The railway station and pedestrian overbridge at Llangollen. The roadway ramp leading down to the station. The iron gate in the open position. The iron fence along the top of the retaining wall. Follow these instructions carefully to perform the Great Escape when trapped inside by a locked gate. (Children under 14 are advised not to try this.) Place the sandwich board sign (located below the number 2 red arrow) against the retaining wall next to the locked gate. Using the sandwich board climb up onto the retaining wall holding onto the black iron fence for safety. Work your way along the top of the retaining wall (away from the camera position) holding onto the iron fence until reaching the far end. Pass around the fence, step down onto the road, and you are free.
