This is the second edition of the popular book published by the Trust in 2001, will be available in hardback and enlarged to A4 size. Each of the narrow gauge locomotive types produced by Motor Rail Ltd and its predecessors is covered in this publication. The book also looks at the locomotive copies made by F C Hibberd and Kent Construction, Margolis and Ralph, and E C Lenning of South Africa. From around 1987, the designs of Simplex Mechanical Handling were continued by Alan Keef Ltd from their site at Lea Line in Gloucestershire.
The second edition now includes 30 colour photographs of Simplexes at work in industry, in addition to the 87 B&W images. There is now a works number decoder, allowing you to find the Simplex model from a works number, as well as a table of locomotives types with the works numbers for each type. Various other updates have been made, including corrections and additions to surviving narrow gauge Simplex locomotives in the British Isles, and this list now includes locomotives in Ireland. The 38 line drawings now include dimensioned works plate drawings detailing some of the changes which took place over time.
The new format is A4, hard cover, with 144 pages, line drawings of various models, works plate details, and over 100 photographs in colour and B&W.
