Second Generation DMUs in Scotland covers the modern diesel multiple units introduced by BR from 1981. It encompasses locations from Aberdeen in the north to virtually the whole of Scotland and also to Carlisle just over the border. This book covers units from the experimental Class 140s, introduced in 1981, right up to and including Class 185s still in use with TransPenine Express. Possibly the best unit introduced to Scotland are the Class 156 units based at Corkerhill Depot in Glasgow. These units can be found working from Newcastle to Mallaig. The new generation of DMU fleets can go faster and travel further and have generated a huge following. Here, Colin J. Howat combines previously unseen historical black and white photography with modern digital examples to tell their story.
