A little further along the river the railway crosses the mouth of Cockwood harbour. Near the shipwreck here was the long Exe Bight Pier, in use from 1869 for about ten years. Dawlish Warren now comes into sight; the sand dunes are home to a nature reserve where many wading and sea birds can be seen. The railway line opens out into four lines at Dawlish Warren railway station, where the platforms are alongside loop lines that allow fast trains to overtake stopping services.
