The Moors Valley Railway is a 7+1⁄4 in (184 mm) narrow gauge passenger railway, in the Moors Valley Country Park at Ashley Heath, Dorset, England near Ringwood in Hampshire. There are 20 steam engines and 2 diesel engines. The railway is fully signalled, with two signal boxes, one in a Great Western Railway style and one in a British Rail Southern Region style. The latter box also contains a mini lever frame and push button panel, for the control of the Lakeside area. The railway was constructed at its present location in 1985/86 and opened to the public in July 1986, after the closure in 1985 of its predecessor at Tucktonia in nearby Christchurch, which had run since 1979.
Moors Valley uses a narrow gauge prototype to produce tank engines in which one may sit, allowing running during the harshest of conditions, so much so that it runs throughout the year. A further benefit of the style of locomotives built to this prototype is that, unlike models, and standard gauge 71⁄4 inch locomotives, the locomotives used on the Moors Valley Railway are considerably more powerful due to the increased boiler size that can be achieved through almost freelance prototypes.Roger Marsh was a pioneer of this principle and built Tinkerbell; when this was spotted a tank locomotive, Talos, was ordered and so started the Tinkerbell-class of locomotives. Coincidentally, when Tinkerbell was seen for sale, it was purchased by the then Tucktonia Railway, becoming its second locomotive. Several more were built at Tucktonia, several far more powerful than previous engines, before everything was moved to Moors Valley Railway.
Moors Valley Railway owns approximately 12 locomotives and a further 7 are privately owned. Hartfield is the most recent addition, being purchased from an owner who rarely used the loco. 'Hartfield' follows the general idea of Jason (a Tinkerbell variation) as per many other private locomotives.
There are many other tender locomotives such as Offa, almost certainly the most powerful 71⁄4 inch gauge locomotive in existence until recently.
The carriages at Moors Valley have no roof, but have a bench in the centre to sit on. Each carriage is approximately eight feet long. There are four rakes of eight carriages, in green, brown, olive and red liveries.
