This facsimile publication is a reproduction of the North Eastern Region’s carriage working book compiled to show the formation and working of coaching stock within the NER and to other regions, excluding East Coast trains. Carriages were mostly formed into ‘set’ formations, which would routinely work a number of trains over one or more days before going onto the work the same roster again or take up another duty. These ‘fixed’ sets were referred to as ‘link’ sets, i.e. they were made of a certain types of coaches giving the required number of seats. For example ‘NE Link B’ sets were formed of 3 carriages; 1 x Lavatory Composite, 2 x Brake Third, the latter with 4 compartments.
