The history of the Metro-Vick diesel family spanned the period 1955 to 1995. This book includes the history of the 20 BR pilot scheme Co-Bos (class 28), as well as the 94 Irish units. Beginning with a survey of all three classes of Metro-Vicks, it concludes with a 24-page colour section illustrating the livery variations over their 40-year life span. Detailed tables of building and withdrawal dates, dimensional tables and a survey of preserved examples are included.
