Although aimed at model engineers, and thus largely devoid of information about poppet valves the book does survey most other types: Stephenson link, Gooch and Allan straight link, Joy (including modified external form), and radial valve gears: Hackworth, Marshall (1879), Walschaerts, Baker, Jones', Beames', Greenly's connected motion, valve gears for multiple cylinders: Churchward and Deeley scissors type and Gresley.

Derived valve gear
The Walschaerts-Gresley valve gear was the source of much criticism, which is partly answered in Holcroft's article, where it is stated that "it may be recalled that in recent times a speed of 125 m.p.h. was attained by one of the L.N.E.R. "Pacifics' fitted with Gresley gear. Cox was involved in a report on the arrangement for Thompson.
