As this Hudswell Clarke loco is back in the museum half of the heritage centre here is a little more information.
Hudswell Clarke & Co.
0-6-0 Saddle Tank No. 431 of 1895
Delivered new to Sheepbridge Iron Works near Chesterfield as their No.15. The loco worked at Sheepbridge and also at the Company owned collieries at Glapwith and Langwith prior to a move to Desborough Quarry, Northamptonshire in March 1951.
The loco came to Chasewater in 1967 after purchase for £195.
Cosmetic restoration only is likely in the near future as the loco is in an advanced state of corrosion.
