- Comparing with the version of 20 May 2008, I'd say that this has since been done. -- Trevj (talk) 11:56, 21 May 2013 (UTC)
- To separate out some complexity, should there be two pages raised from the present page, one titled "Clerestory - Architecture" and the second "Clerestory - Transportation"; possibly with a header page just "Clerestory", providing a link to what in effect would be 2 sub pages as just described? --Terry nyorks (talk) 22:29, 19 May 2014 (UTC)
I'm not sure the VW is a valid example of clerestory windows as there really isn't a distinct break of the roof into two sections, nor are the upper windows vertical. ++Lar: t/c 04:58, 5 January 2014 (UTC)
- Don't know - I think you are probably right - does it have a name of its own?? Prof.Haddock (talk) 16:53, 7 January 2014 (UTC)
Definitely not a clerestory roof, using the US definitions applied in "A Railway Car-Builder's Dictionary" as a reference.
Transportation : Railway Coaches
The first recorded Clerestory Roofed Railway Coach preserved in the UK was the coach "Midland" referred to in the article, i.e. the 1874 coach. It is currently at Midland Railway Centre, Butterley, albeit now in a poor condition, almost skeletal, and consequentially being preserved that way.
I am not so sure about the statement 'from the mid-19th century' in the previously unedited first transportation paragraph, if treated unqualified (so I have added 'in the USA') - and will have to check this out at the National Railway Museum when I'm next at the search engine. The oldest preserved coach in the UK, listed chronologically by build date is indeed the Pullman "Midland" ("Preserved Railway Carriages", Michael Harris, Ian Allen 1976, (ISBN 0 7110 0664 4). So the Pullman Import (to the UK) design was relevant to the subsequent design of roof outlines of Railway Coaches here.
Of course, in the US, the roof design was in use earlier, the George Pullman first fully own designed coach was "Pioneer" in 1864; the coach then being used in Pres. Lincoln's Funeral Train in 1865 (as being the most impressive 'railroad car' - US vernacular - available at that time, and tradition says the choice of Mary Todd Lincoln). This of course provided notoriety and impetus to GP's fledgling business. (Fuller background - and [[File:https://www.flickr.com/search/groups/?z=t&w=2031425%40N22&m=pool&q=Lincoln%20funeral%20train Lincoln funeral train] ).
As to earlier built clerestory roofed coaches, I have been unable to research earlier than 1865 (US) or 1874 (UK) vehicles, so far.
The Romans were the first known to use glass for windows, a technology likely first produced in Roman Egypt. Namely, in Alexandria ca. 100 AD cast glass windows, albeit with poor optical properties, began to appear, but these were small thick productions, little more than blown glass jars (cylindrical shapes) flattened out into sheets with circular striation patterns throughout. It would be over a millennium before a window glass became transparent enough to see through clearly, as we think of it now.
- So you are right, although it seems to have turned up in Egypt first! LynwoodF (talk) 15:12, 12 September 2017 (UTC)
