London & North Western 0-8-2 Locomotives in Great_Britain

Class Details by Steve Llanso of Sweat House Media

Class 1185 (Locobase 2204)

One of several freight-engine classes that used the 23.60-sq ft grate

Chris Northedge, author of the [] (10 May 2003 -- the website of the London & North Western Railway Society's Goods Locomotives "exhibit" describes its origins.

This was a CJ Bowen-Cooke heavy shunter design that made use of the basic G-class boiler and grate and added a trailing pony truck. Northedge notes that like the other 0-8-0s, the third driver was flangeless and the coupling rods came in 3 parts to handle sharp curves.

The last of this class retired in 1953.[1951, says Northedge]
