The Royal Gunpowder Mills


13'6" X 1'6"

For 200 years the Royal Gunpowder Factory at Waltham Abbey, Essex, manufactured gunpowder and in later years cordite.  An extensive canal system was used for transport within the factory and sailing barges took finished products to Woolwich Arsenal.


This layout features an 18 inch gauge railway system which was first installed in 1917 and then extended in the inter-war period, using diesel and battery powered locomotives.  On the model a few of the hundreds of explosive production and storage buildings have been re-arranged to form a linear diorama.


9mm (N gauge) track is used for the 18” railway so everything is to a scale of 6mm/ft.  All buildings, trains and boats are scratch built from original drawings, direct measurements and photographs.


The Royal Gunpowder Mills has been open to the public from 2001 - for more information visit:
