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]
