WW1 also brought an urgent need for more munitions, and in 1915 the Ministry of Munitions created many national munition factories. The National Filling Factory No 7 in Hayes, Middlesex had an explosives magazine at Northolt which was completed late in 1916. This 93 acre site had 20 stores each able to hold 100 tons of explosives, and was connected by a rail spur at Northolt Junction station. The location was just North-East of the current Ruislip Gardens station, with the rail spur on the south side of Yeading Brook, and the magazines connected by trolleyways on the North side. About 100 tons of explosives per day were sent by rail to Hayes for filling artillery shells - both the Hayes factory and the magazine were removed after the war ended.
