[3] Originally, the colliery had its own branch from the Coventry Canal, but in 1919 with the return of the men from the First World War, production increased.
A separate and new 2 miles (3.2 km) private railway was constructed from the LNWR's Coventry to Nuneaton Line at Three Spires Junction.
By 1939, the last year of full production before the Second World War, the colliery was producing over 1,000,000 long tons (1,000,000 t) of coal per annum.
[4] This came into production in 1967, and resultantly in an NCB reorganisation the Coventry Colliery became part of the South Midlands Area (SMD).
[3] But the large amounts of spoil created, and the reduction in shipping charges associated with building materials, necessitated the building of a temporary 2 miles (3.2 km) private railway, which connected with the London & North Western Railway's Coventry to Nuneaton Line at Three Spires Junction near Foleshill.
The line was hence rebuilt as double track with extensive sidings adjacent to Three Spires Junction, and formally used for the distribution of extracted coal.
All three were sent to Andrew Barclay Sons & Company in Scotland for refurbishment before use on the colliery system, and their being brought into operation resulted in all of the other existing standard gauge locomotives being scrapped onsite.
[1] The three 1500 Class locomotives were sold into preservation at the Severn Valley Railway, with 1502 and 1509 providing a kit of spares to refurbish 1501, before they were scrapped at Cashmore's, Great Bridge in October 1970.
