Class Details by Steve Llanso of Sweat House Media

Class Brookfield (Locobase 8571)

Data from [], the Foxfield Railway Virtual Stocklist ([]) and the Pontypool & Blaenavon railway site ([], all accessed 14 July 2007.

Locobase wonders at the description of this design as a pannier tank. Photos show the tanks flanking the boiler rather than sitting on it; also noticeable are the compact lines in general and the pleasing capped stack. In any event, Brookfield's outside Walschaert gear stamps it as a relatively unusual industrial locomotive.

Foxfield tells us that Brookfield 2613 was one of 4 Bagnall engines commandeered in 1940 for the war effort and converted from the Turkish gauge to standard gauge. It was put to work on the Admiralty Machinery Depot in Stoke-on-Trent, where it operated until its retirement. By that time, the facility had been renamed the Brookfield Foundry.

Stored from 1961 to 1983, Brookfield 2613 was reconditioned and restored to museum service. In 1993 it joined the Mangapps Farm Railway Museum at Burnham on Crouch, Essex. Locobase has no information about the other 4, but presumes they were scrapped.
