Data from John Weale, Benjamin Franklin Isherwood, Edward Dobson, Ensamples of Railway Making: Which, Although Not of English Practice, are Submitted, with Practical Illustrations, to the Civil Engineer, and the British and Irish Public (Architectural library, 1843), p. xx.
Boiler pressure is a Locobase estimate. The authors say this design was used in light traffic and reached 20-25 mph.
NB: Evaporative heating surface area estimate derived by adding reported direct heating surface to calculated tube heating surface.
