Mechanical Details
Innovations included double chimneys on certain members (the only GWR class ever to have double chimneys fitted by the GWR) and a high boiler pressure of 280psi (though this was later lowered in an attempt to reduce maintenance costs). Modified double chimneys were fitted to all the class from 1956. They also pulled Hawksworth slab-sided tenders, as fitted to some of his modified Halls and retro-fitted to many earlier designs; however the County tenders had a water tank six inches wider than the tenders built for the Halls and earlier designs.
The running gear of the County was almost exactly the same as Hawksworth's earlier Modified Hall Class. The boiler however was a development that used the tooling for the LMS Stanier Class 8F boiler, Hawksworth being able to study this design closely when 8Fs were being built at Swindon as part of the war effort.

Famous quotes containing the words mechanical and/or details:
“A committee is organic rather than mechanical in its nature: it is not a structure but a plant. It takes root and grows, it flowers, wilts, and dies, scattering the seed from which other committees will bloom in their turn.”
—C. Northcote Parkinson (1909–1993)
“Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.”
—Willard Van Orman Quine (b. 1908)
