LYR Carriage Diagram Book
The carriage diagram book was a document used by operating staff to determine the most appropriate stock to use for any given traffic requirement. It contained a plan view of the vehicle showing the accommodation and capacity of each type of carriage. Updates were issued to each holder and surviving examples vary. This copy has been produced following careful examination by Mike Fitton of a number of versions and we recommend careful reading of his introduction as an aid to understanding the individual diagrams.
