This fantastic new reference book looks at the lines around Portsmouth Harbour that were operated mainly by the Admiralty and the Military, far from the public gaze. These secretive systems were often obscured by high walls, and most glimpses would have been through closely-guarded gates, with the occasional sight of a train joining the main line. This book brings together data, illustrations and potted histories to give an insight into the locations and operation of these concealed railways. Of prime importance to Portsmouth is the naval dockyard which was home to over 50 locomotives over the years, but other associated facilities included the Naval Armament Depots at Gosport, the Gunnery School at HMS Excellent on Whale Island and the Army s presence at Hilsea Ordnance Depot all of which are included. Alongside several large scale construction projects, the dockyard branch lines are also included. The industrial railway at Hilsea Gasworks, and Pounds Yard at Tipner, which were beyond public access also fit well into this volume. Featuring over 200 black and white illustrations and a variety of unseen photographs this new title forms an interesting history of the Dockside Railways and the locomotives that used to work there.
