When is a 0 (zero) used instead of lower-case 'o'? I never see that. —Morven 17:03, Dec 1, 2004 (UTC)
I've seen it in rail road mags and model catalogues. Plus some web sites: [1]
Or Google for "wheel arrangement" B0. You get a pretty big list.

Is the final prime in B'B' needed? What about Bo'(A1A), the prime in the middle looks superfluous... Finally shouldn't 1′D1′ be 1'D'1 if the final axle is in a bogie of its own? Railwayfan2005 ( talk) 20:43, 23 April 2008 (UTC)
UIC Kodex 650 page 4 writes "an apostrophe" for wheels in separate frames. So why call this a prime? -- Sveins ( talk) 22:07, 4 April 2010 (UTC)
The UIC also has classification systems for locomotives, passenger coaches and goods wagons. See the articles on UIC identification marking for tractive stock, UIC classification of railway coaches and UIC classification of goods wagons. Shouldn't this therefore be retitled something like UIC classification of locomotive axle arrangements (or shorter still UIC locomotive axle classification) to distinguish it from the others? -- Bermicourt ( talk) 22:11, 11 March 2009 (UTC)
The Southern Railway once used a different system, but did not other class remain as they were before? Tabletop ( talk) 08:07, 15 March 2009 (UTC)
Perhaps it's good idea to link to an articles about a real locomotives for each example given?-- ospalh ( talk) 10:37, 5 February 2010 (UTC)
The example for brackets mentions Mallet, but cites the Big Boy, which (if I understand correctly) isn't a Mallet, only an articulated (the distinction being the compound expansion.) Wouldn't the text more correctly read " Mallet and other articulated locomotives can be indicated..." (emphasis mine.) -- 65.215.221.182 ( talk) 21:12, 18 November 2010 (UTC)
This reference is inaccesible "Standard designation of axle arrangement on locomotives and multiple-unit sets" (PDF).

The article states that a lower case 'o' means each axle has its own electric traction motor. While that is definitely the most common situation, the DRB Class 19.10 had a separate steam motor for each axle and got classified as a 1'Do1' in all the literature I could find about it. So shouldn't it simply read that each axle has its own driving motor, instead of saying that it has to be electric? — Preceding unsigned comment added by 79.198.53.171 ( talk) 20:37, 27 February 2012 (UTC)
@ Andy Dingley, Voidxor, Tabletop, and KnightMove: do you know why the lead says this is "also known as German classification"? German classification redirects here because...? The cited source The Railway Data File. Published by Silverdale Books 2000. p. 52. ISBN 1-85605-499-3 seems to lack things like a named author. Who is Silverdale Books? Do any other sources say this is known as German classification?-- Dennis Bratland ( talk) 20:08, 18 January 2018 (UTC)
Why is it marked as a hypothetical example? There was actually such a locomotive class, the Bavarian Gt 2×4/4, which had this axle arrangement and was even classified as a Freight Traffic Locomotive by the Reichsbahn in 1923. Universal-Interessierter de ( talk ( de)) 23:14, 22 July 2022 (UTC)
