Written by David Ratcliffe, an expert on wagons, this heavily illustrated title shows the wide range of air-braked wagons, both revenue types and departmentals, that BR owned themselves and operated from the mid-1970s, providing coverage of the third main groups of wagons to be found in use during the period. The book starts with an introduction covering the reasons behind the introduction of air-braked types before providing listings of the TOPS codes allocated and examining some of the experimental designs initially built.
