The Severn Tunnel Junction was the largest freight marshalling yard on the Western Region of British Railways, once stretching for over two miles along the Welsh bank of the River Severn. At its height it was a goods yard, junction, station and loco depot, but it was an important railway community and small town as well. With more than 150 photographs this book describes the beginnings of the yard within the wider historical context and discusses the expansion of the site and the impact of the two World Wars. It documents the methods of working at the junction and recalls the locos, freight and passenger trains that travelled the lines. Finally, the people who worked and lived there are remembered.
