The Millers Green Light Railway is of course fictional in it's nature, but in essence, covers an area which is very much in existance. Millers Green is located just under a mile to the south west of the village of Wirsworth in the southern environs of the Derbyshire Peak District, and approximately half a mile to the west of the 'Wirksworth Branch' of the North Midland Railway, latterly known as the Ecclesbourne Valley Railway.

The area occupied by the MGLR was noted for it's diversity of produce, thus allowing the running of mixed trains with a variety of rolling stock. The hills towards the north west of  Millers Green were extensively worked for mineral deposits of Fluorspar and Galena in the latter part of the 19th century, as well as extensive deposits of limestone worked for a multitude of uses.
