In another example, the Ministry of Supply (MOS) Factory Dalbeattie used 2 ft 6 in (762 mm) gauge with a variety of bogie trucks mostly pushed by teams of three to six women.
Stores, explosives, chemicals, rubbish and sewage, were all transported on this narrow-gauge system, which used at least 8 miles (13 km) of track.
These factories were created during WW1 to unite the explosives, detonator, etc and the shell casings to make live munitions.
Records exist of two Baguley 2 foot gauge internal combustion locos ordered in 1917 by No 7 National Filling Factory for Northolt.
[20] Seven similar locos were ordered in 1917 for No 2 National Filling Factory at Aintree,[20] so this must also have had light rail outside the main assembly area, such as for storage of shell cases (as this factory was designed to handle ship loads of munitions components received from overseas at Liverpool Docks).
