Geoffs trains tours
Built by Beyer Peacock in 1953, the class 14A is an update of the 1929 built 14th Class. Innovations included self-adjusting
pivots with spring loaded side bearers. The front and rear bunkers were streamlined and fitted with spring loaded bolts to
allow for slight movement whilst running. A Hadfield power reversing gear was fitted.
The fleet was numbered from 508 to 525, a continuation of the remaining 14th Class locomotives which had been renumbered
500 to 507.

# 509 is preserved in New Zealand
