Published last year by the Industrial Railway Society was Industrial Railway Locomotive Sheds by Adrian Booth. The author may be known to you if industrial railways are of interest. Irwell Press have published a selction books with his wonderful colour photos.
In the beginning there were only industrial railways - in many ways industrial railways are railways in their purest form and they can be a world away from the 'mainline'. All too often modellers try and model them in a similar to the way they would any other subject. This is a shame as it almost misses the point. For many it's these differences (not too mention steam's continuation far beyond 1968) which appeal and give industrial railways their own special charm. The variety is immense too - some indsutrial locations, especially those which required the use of fireless locos, can provide sites which are very clean, almost clinical and quite unlike the railways beyond their site's confines. Similarly there can be those which are filthier than any thing that most enthusiasts or railwaymen have experienced.
This variety and non-conformity is well illustrated throughout the book. The locations featured provide all sorts of contrasts - from Stewart & Lloyds' Corby site where the shed looked very much like a contemporary 'modern' BR establishment to a rather ramshackle affair at Idhurst which looks like the encroaching trees are holding the structure up! It's an excellent book, especially if you're interested in industrial railways.
