Editing LMS Coronation Class (section)

==== Pre-1951 ====
Early in 1948, before the new liveries for the whole of British Railways had been decided upon, Nos. 46229, 46232 and 46236 were repainted LMS-style lined black (crimson and straw lining){{r|Baker|p=64}} and No. 46257 was similarly turned out when constructed in July.{{r|Jenkinson|loc=Plate 199}} Throughout 1948 and 1949 the English locomotives (now under the control of the [[London Midland Region of British Railways]]) were relined in an experimental BR lined black,{{r|Hunt|pp=143, 148, 150, 166}}{{r|Jennison|p=51}} which used LNWR-style red, cream and grey lining (similar to that adopted for Mixed Traffic locos), and 'BRITISH RAILWAYS' in Gill Sans on the tender.<ref name="Rowledge87">{{cite book |last=Rowledge |first=J.W.P. |year=1987 |title=The L.M.S.

The Scottish locomotives based at Glasgow's Polmadie shed, which were under the control of the [[Scottish Region of British Railways|Scottish Region]], were destined for a brighter future. Commencing in May 1948, seven of the class were called in to be painted in "experimental blue". This livery was a somewhat darker shade than that adopted as the standard express livery the following year, being more similar to the former [[Great_Eastern_Railway|GER]] blue, and lined out in the LNWR style lining with 'BRITISH RAILWAYS' in Gill Sans on the tender.{{r|Rowledge87|pp=21, 22}} So sudden was the adoption of this blue livery that No. 46232, fresh in LMS-style lined black following its heavy general repair, was called back after a mere four days to be repainted blue.{{r|Baker|pp=64, 112}} Around this time BR was also experimenting with various shades of green on the other regions.{{r|Banks|loc=Rear jacket}}

The Polmadie experiment was upheld by British Railways in 1949 when the somewhat brighter BR standard blue was selected for all its large passenger locomotives, despite the fact that the [[Great Western Railway]] (GWR), the [[Southern Railway (UK)|Southern Railway]] (SR) and the London & North Eastern Railway (LNER) had overwhelmingly painted their locomotives green (the LMS by contrast concentrating on crimson lake). Blue was subsequently carried by 27 of the 38 Coronation Class locomotives. The first two to be so painted, Nos. 46242 and 46243 were outshopped in the new colour when they received their heavy general repairs in May 1949.{{r|Baker|pp=64, 144, 148}} The blue livery, which was subsequently phased out, lasted until September 1955.{{r|Baker|pp=64, 186}}

British Railways undertook a massive programme to establish itself by repainting all its locomotives with their new BR numbers and replacing their previous corporate identity with its own. Gone were the tenders proclaiming the railway companies' logos, emblems and even coats of arms, to be replaced by the stark <small>BRITISH RAILWAYS</small> lettering. The enormity of this task meant that the necessary repainting was not necessarily carried out to coincide with an overall repaint. For the Coronation Class, all locomotives had been through this process by the end of 1948 except for Nos. 6223, 6238, 6248, 6250, and 6252–6255, a total of 29 locomotives.{{r|Banks|pp=147–148}} Only thirteen locomotives out of the 29 received new liveries to accompany their renumbering.

Subsequently, in 1949 a crest was designed to replace the spartan <small>BRITISH RAILWAYS</small> logo. In turn, this would be replaced in 1956 by yet another design of crest.<ref>{{cite book |last=Jackson |first=Tanya |title=British Railways: The Nation's Railway |date=2013 |publisher=[[The History Press]] |location=Stroud |isbn=978-0-7524-9742-6 |chapter=6}}</ref>
