Locomotives, coaching stock, goods wagons and other miscellaneous items resident on the railway, as at January 2016, are fully described. An effort has been made to present a reasonable up-to-date history and technical appraisal of all items in the collection wherever possible. With such a large operational railway, changes in the rolling stock register are frequent - new items arrive, while others depart, some are stored for overhaul, while others are restored to their former glory. Overall, the gains outweigh the losses, so for each edition of this publication my task has become just that little more involved. The efforts of the railway's staff - paid and volunteer alike - who restore and maintain the various items of rolling stock are very much in evidence, the standard achieved being a credit to their craftsmanship and enthusiasm. This Stockbook is intended to complement the official West Somerset Railway Guide Book, which I recommend for your further reading. I sincerely hope that you enjoy your visit to the West Somerset Railway, and that this publication gives you a deeper understanding of both the train in which you travel and of the other items you see on your trip.
