This article was written quite poorly. The author's command of basic English needs to be reviewed. — Preceding unsigned comment added by 71.163.216.109 (talk) 17:46, 19 January 2007 (UTC)[reply]

More careful description and taxonomy needed, not mere grammatical objection

I do not think the issue is, or is not, whether the poster's English skills are lacking; that's the inherent responsibility of other 'editors' in the Wikipedia system.

A more important issue concerns what this design of locomotive actually accomplished, and (more importantly in my opinion) how the actual mechanical design was laid out. At least one graphic clearly showing the running gear needs to be found, proper permissions to post it secured, and linked appropriately to the subject page. That would more properly guide us toward what this locomotive represents.

I have found such a graphic, and some information on the locomotive, here:

My opinion at this point is that the locomotive is a BALANCED design, and as such should be put in a section describing locomotives whose running gear is designed for inherent balance -- the Shaw locomotive of the early 1880s and the Withuhn conjugated duplex of the early 1970s being two immediate examples that come to mind, and some 'flavors' of four-cylinder simples and compounds (I have not done this research to properly-exhaustive standards). Note that a locomotive such as one of Churchward's 4-6-0s which is 'quartered' by side is not truly 'balanced' in the same sense one with 180-degree adjacent cranks is; this applies to most of the de Glehn/du Bousquet four-cylinder locomotives as I remember them also)

Perhaps it might be noted in this place that there is an ANTITHETICAL way to implement four cylinders in 'balance' -- that being either to mount them in line on a common piston rod, as in 'tandem compounds', or have them bearing on a common crosshead as in the Vauclain compounds...

History

I'm not sure what country Prague (Praha) was in in 1861 because the Austro-Hungarian Empire was formed in 1867 and Czechoslovakia in 1918. Biscuittin (talk) 22:03, 4 October 2013 (UTC)[reply]

Probably Bohemia. Biscuittin (talk) 09:16, 5 October 2013 (UTC)[reply]
