..........though probably not in breakdown cranes. Secondly - for interest - see http://www.museumofpower.org.uk/Archive ... 20Book.pdf ...........and never forget to look at Grace's Guide ... http://www.gracesguide.co.uk/Cochran_and_Co_(Annan)

Most certainly in breakdown cranes! The boilers the GWR built c. 1917 for use in Nos 1, 2, and 3 were all dry-head VFT (vertical firetube) boilers, and one has survived, albeit in poor condition, with No 2. Were it not for the unexpected availability of the superior, and better condition, Cochran Hopwood boiler from DS1560, the GW VFT boiler would have been overhauled for reinstallation in No 2. By all accounts a VFT boiler is a crude and very inefficient design, and the reason the GW opted for this is unclear, but may well have been due to patent restrictions. The boilers were, I imagine, produced "in house" at Swindon due to the war work going on elsewhere, and it may simply be that the GW either could not, or declined, to seek a licence to manufacture a Hopwood design. |
