The author's particular fascination with the railway line running between Bristol and Bath has lead him to record in detail the history of this fascinating and important stretch of railway, a microcosm of many British main lines. The line has most of the representative engineering features, from embankments and bridges to tunnels and water troughs, and it has seen all the significant types of motive power, from Churchward's 4-6-0s and the first English Pacifics to GWR railcars and prototype HSTs. Colin Magg's affectionate and accurate depiction of this route should be of interest to all railway enthusiasts, modellers and those keen to learn of the history of the GWR. Fully illustrated with maps and over 200 photographs, this authoritative study provides a rare insight into the development of a typical part of the British railway.
