Accucraft Trains is pleased to announce this locomotive in 7/8ths” to the foot (1:13.7) scale live steam. Our thanks and appreciation to both Graham Langer and Ian Pearse for their assistance in the development of this model.  In the UK the model has been produced in association with Kent Garden Railways and will only available from them or direct from Accucraft (UK).


Kerr Stuart produced 163 ‘Wren’ type locomotives before they ceased trading in 1930 and a further four were constructed thereafter by Hunslets.  The ‘Wrens’ owe their origin to the ‘Buya’ class of 1903 although the type encompassed a huge number of variations including inside and outside frames and inside and outside valve gear.  Our model is based on the 2’ gauge ‘new type’ developed in 1915 with inside frames, Hackworth valve gear and cast-iron wheels fitted with steel tyres.  In due course ‘Wrens’ were sent around the world, many to Africa and Asia whilst in the UK they found homes with construction companies and the Ministry of Munitions, some being used by the Ministry of Defence in the building of airfields.  No fewer than 27 were purchased by R.H.Neal & Co. for sewer contracts and several of these were sold on to Devon County Council for road construction.  A few ‘early’ type ‘Wrens’ survive around the world and half a dozen ‘late types’ have been preserved, five of them in the UK.


The model is internally gas fired and has slide valve cylinders with working Hackworth valve gear. The boiler is fitted with a water gauge with blow down valve, lubricator and pressure gauge. It will be available in 45mm gauge (gauge 1) only.
