‘Sabrina’ is a freelance locomotive with design inspirations from Manning Wardle aimed at providing a robust, entry level model which is easy to maintain and operate. Although the design is still outside-framed it now has the sophistication of simplified Walschaerts valve gear and slide valve cylinders for a smoother performance and enhanced delivery of power.
The locomotive is internally gas fired with a centre flue boiler. The model is gauge adjustable from 32mm (‘O’ gauge) to 45mm (‘1′ gauge) and has insulated wheels as standard. The axles run in bronze bearings and all the rods and valve gear are manufactured from stainless steel. The cab roof flips up and over sideways to give access to the gas, water and lubricator fillers. The boiler is fitted with a water level check valve and the displacement lubricator has an under-floor drain valve. The model is built from stainless steel and brass.
