This set is steadily growing but does not yet cover all preserved railways and coaching items.

Items are organised by the "Big Four" companies, MK1, MK2 and MK3 etc.

Class names generally conform to the pattern {Constituent Railway/CME} {Classification} {Diagram} eg "GSWR TK (42)" is a Glasgow and South Western Railway Corridor Third, built to diagram 42.

The excellent Railway Heritage Register is used as a reference for classification and diagram.

For coaches built for the big four, the CME name is sometimes used, eg "Gresley SLF (157)".

Not all classes follow this pattern, but we are updating as time permits.

We are also starting to split up MKII coaches into 2, 2a, 2b etc
