20057 & 20154 Ollerton Colliery 28 June 1992

The huge concrete rapid loading bunkers of Ollerton Colliery dominate this view of 20057 & 20154, as they work the Worksop Open Day Committee 1Z29 'Worksop Whistler' railtour on 28 June 1992. Class 20s, coal mines and semaphore signals - all things that have rapidly declined since this picture was taken.
