Editing LMS Coronation Class (section)

==== The final locomotives ====
The final two locomotives Nos. 6256 and 46257 ''Sir William A. Stanier, F.R.S'' and ''City of Salford'' were given many new features. In order to raise the mileage between general overhauls from 70,000 to 100,000, measures were taken to decrease wear to the axle bearings and [[hornguide]]s through the use of roller bearings and manganese steel linings. Other modifications included further superheating area, a redesigned rear frame and cast steel trailing truck, rocking grate, hopper ashpan and redesigned cab-sides.{{r|Roden|p=64}}{{r|Nock84|p=146}}
