4 Built in Britain page 81. In stating that compounding and superheating were alternatives the author Michael Bailey perpetuates the fallacious argument of Dr. Robert Garbe, the Prussian Railway engineer, whose views, where they were accepted, materially retarded the thermodynamic improvement of the railway locomotive.
5 The illustration reproduced on p. 121… believed to be Nasmyth’s erecting shop … is misleading. It is Nasmyth’s drawing of Maudsley’s erecting shop and exists in at least three versions. The first does not include Maudsley’s engines for the paddle steamer Dee, r, h, side, the second does and the third, shown here, adds the locomotive production line on the l.h. side. The prominently shown cast-iron roof collapsed on the 24 May 1826 as a result of faulty design. No evidence has emerged to show that a building of this design existed on Nasmyth’s Patricroft site.

7 Langridge, not the most unbiased of commentators, maintains that much of Derby’s work was directed towards shaking off the Great Western influence that Stanier tried to import. Langridge op. cit. Vol I Chap. 8.

14 It is notable that Britain had to turn to France for deep expertise in locomotive riding analysis. Leguille was an expert on bogie kinetics through his association with S.N.C.F. electric locomotives.
