Why the brackets? Compare 4-2-2-0. Biscuittin ( talk) 10:59, 19 March 2012 (UTC) reply

Not sure why this is - that is the way they are referred to in Baxter's Catalogue and also other books on the Webb compounds. However, I note that H.C. Casserley (The historic locomotive pocket book (London: Batsford 1960) pp.117-8 refers to them as 2-2-2-0. Also O.S. Nock (British locomotives of the twentieth century vol. 1 (London: Patrick Stephens, 1983) p.180, refers to the Great Briutain class as 2-2-2-2 so perhaps it doesn't really matter.-- Das48 ( talk) 08:29, 4 June 2012 (UTC) reply
