When I first added material to the “EMD E6” page, I included 90 words about the A1A-A1A wheel arrangement. This was all right for one page, but I wanted to add the same wheel arrangement material to all the EMD E-unit pages, a total of nine pages. Text would be needlessly duplicated. So I moved the A1A-A1A wheel arrangement material to a new page, “AAR wheel arrangment”, and added material for several other wheel arrangements. That way, myself or anyone can internally link to the section within “AAR wheel arrangement” that corresponds to the desired wheel arrangement, and eliminate some text duplication.

I don't see a point of adding a chapter for "Steam Locomotive Wheel Arrangement" since it is already covered in articles for Whyte notation and UIC Classification. Removed. Z220info 14:38, 22 March 2006 (UTC)
I found the initial article very confusing to read, especially given that to understand anything of the differences between the three main notation systems (AAR, UIC, Whyte) one had to click on each link in turn. So I set to work rephrasing several words and passages, and reordering the run of sentences etc. There were also some inconsistencies in the article - three bullet points at the end of the article contradicted statements in previous paras, causing reader confusion about whether or not Whyte notation is used in the US. So I checked all thoroughly while reworking the whole, so as to give a proper "overview" of the subject. Lastly I tried to find any decent sources - there are loads on the web describing the various steam wheel arrangements, but almost nil about the overall nature of wheel arrangements as a subject, ie. why and how they matter. Finally found one source that defined it reputably as "the distribution of wheels under (etc)", and referenced it accordingly. The article's still not great, but at least it's now a whole lot better to read / easier to understand. Hopefully others will agree. Pete Hobbs (talk) 01:52, 2 August 2011 (UTC)
