The Birley Collieries were a group of coal mines set in the Shire Brook Valley in south-east Sheffield, South Yorkshire, England. They were connected to the railway system by a branch line from the Manchester, Sheffield and Lincolnshire Railway at Woodhouse East Junction, about 800 yards east of Woodhouse station.
From 1877 to his death in 1926, William Dunn Gainsford was owner of the Birley Collieries, with his cousin Alfred John Gainsford serving as Managing Director.[1]
