The Crewe to Swansea night mail crashed just outside Shrewsbury. The train was derailed on the steep curve by Crewe Junction signal box ploughing a furrow before falling over and taking most of the coaches with it. The speed limit on the sharp curve was 10 m.p.h, but the train approached at full speed. The exact cause of the accident has never been fully explained. Large numbers of people gathered at the abbey where a double funeral took place for the two GPO men.
