I'd heard of it, without knowing where it was though.
Interesting photo, the standard gauge shunter is ex BR Class 02 D2865, arrived from BR at Goole in 1970.
Two different styles of narrow gauge shunter on the left, the yellow one is a 104hp Motor Rail loco, delivered new in 1974, and the white one on the right is one of a pair of Ruston & Hornsby "100DL" locos built in 1949, they worked there from 1952/1959 until the place closed in March 1984.
On closure D2865 moved to Beeston Cement Terminal, wasn't used there and would be scrapped by Vic Berry in 1985, the Motor Rail would pass to the Shane's Castle Railway via Alan Keef, one of the Ruston locos was scrapped, the other one ended up with the Irchester NGRT, no idea if it still exists though.
Fascinating photo, thanks for posting (same applies to the whole thread BTW!)
(And...)
Newstead Colliery, the shunter's an 0-4-0DH with a trusty 203hp Gardner under the bonnet (HE5623/1960)
Cheers,
Andy.
