Renowned as the "Cradle of Railways", the North East of England has always had heavy freight traffic. During the era of the First Generation diesels of classes 20, 31, 33, 37, and 47, the region probably saw more changes than anywhere else on the old British Railways system. We show these locomotive classes, together with shunters of class 08, working in the 1980s, 90s and 2000s. Shots include main and branch lines including on Tees-side and Tyneside, Humberside and in Yorkshire. This fabulous programme, part of a wonderful eight-volume series, celebrates the might of diesel, an often overlooked part of British rail heritage. Incredible action footage makes every title in this series a real treat.
