Firstly, this is a hardback book rather than paperback as listed in the current description. It's one I'd recommend for the S&D fan/modeller - not general railway interest. The photos are interesting from an historical perspective but this is not a 'professional photos of trains in the landscape' railway book in the way of (e.g.) Heyday of the Warships. If you are interested in the end of the S&D - after withdrawal of the through express trains in 1962 (steam hauled coal freights, local passenger service and final specials) and post closure developments (coal movement at Radstock, track lifting trains with DH Class 22s and 35s) then you will find this book interesting. A few minor quibbles - a couple of the photos of Bath Green Park early in the book are printed the wrong way round - anyone who knew the station will immediately see something is wrong. On the plus side there are some interesting shots - the post 1966 Radstock based diesel shunter off the rails at Writhlington in 1969 with on-looking bemused railmen and grass growing all around, captures the era and the atmosphere of the Somerset coalfield - embedded in the countryside - in a superb way. I was also surprised to see the diesel shunter moving 16T coal wagons around Radstock in 1972 - I remember the introduction of larger 'Merry-go-round' coal hopper wagons before final closure of the coalfield in 1973 that I thought involved some track re-alignment at Writhlington - was that all done (if it was!) just for less than a year of further operation? There is also some coverage of the Midland line to Bristol via Bitton, Mangotsfield and Staple Hill. I've rated this with four stars - but as I used to travel from Bath GP to Staple Hill on the train service and lived near Radstock I'm probably not the best person to advise!
