The first public passenger railway in the world, the Liverpool and Manchester Railway, still sees heavy traffic today. Its many branches and rivals, north of the Mersey to the Scottish Borders, have been the haunts of the great variety of British Diesel locomotive types. Examples of classes 20, 31, 37, 40, 47, 50 and 55 are seen at work in the final two decades of the 20th Century. We also take a circular tour from Liverpool to Manchester via Carlisle with a heavy concentration on coal traffic. 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.
