Data from tracing archived at [], last accessed 26 July 2015. (Thanks to Abhijit Gore for his 28 November 2024 email correcting the locomotive operator's name.) Works numbers were 332-336 in 1853.
Although the original documentation gave the locomotives' owner as Peto, Brassey & Betts, the class instead went to work on the EIR. BP&B's expertise lay in providing contractor services. According to Abhijit Gore,the firm never operated in India.
Moreover, wrote Gore, the two main sources presented different information describing Vulcan's works 332-336, which seem to be the actual
Data from Ernest Taillard, Exposition Universelle de Paris de 1867-Chemins de Fer-Les Locomotives et le Materiel de Transport, 1ie Volume (Paris: Dunod, 1867), pp.38-39.
Data from D[aniel] K[innear] Clark, "On the Locomotive Engines in the International Exhibition of 1862," Newton's London Journal of Arts, (1 January 1864), p. 34.
A "standard" class of outside-cylinder 2-4-0s built for the railroad over a seven-year period by a variety of British builders. Data are of the WG Armstrong & Co. batch. Avonside, Hawthorn, Canada Works, Kitson's, J Morrison (10 in 1867), Cross & Company. Kessler of Esslingen and Escher Wyss of Zurich also contributed engines. (Thanks to Werner Hardmeier for his 5 January 2022 email asking for more information on the Escher-Wyss contribution to this large class.)
(Hardmeier pointed out that Escher-Wyss built only 35 locomotives before moving on to specialize in "paddle steamers an other technical items.") The 10 sent to East Indian represented slightly less than 1/3 of the total. Works numbers were 51-60 in 1866; EIR road numbers were 366-375.
Clark, a well-known designer and commentator on steam locomotives of the time, commented that the tube diameter of 2 1/4" meant the tubes were laid in the boiler at only a .56" (14.2 mm) spacing.
"These proportions would", in Clark's opinion, "be improved by reducing the tubes to 2 inches diameter, with increased clearance; and the reduction of heating surface would be amply compensated by the increased facility for circulation of the water and steam between the tubes." Such discussions would recur frequently throughout the age of steam.
Data from John Bourne, CE, Recent Improvements in the Steam-Engine (London: Longmans, Green & Co, 1880), p. 243.
Bourne says little specific about this locomotive (which he credits to "Kepler of Wurtemburg [sic]") other than to note that it appeared at the 1867 Paris Exhibition. The official report of the United States Commissioners singled out this locomotive as an example of how new manufacturers were competing successfully for business.
