KMRC Skrifa – Modelling the BR diesels Green to blue period
This subject of locomotive liveries especially between the mid 1960s and early 1970s can get very complicated and as with all aspects on railway modelling it is always best to refer to photographs whenever possible.
The original livery for the diesels was black with a silver waistband strip but this was replaced by versions of green from 1956.
Diesels were originally numbered with a D prefix to a four digit number (electric locos had an E prefix) after the end of steam in 1968 the Prefixes were dropped. British Rail then introduced the now familiar Total Operations Processing System (TOPS) numbering system in 1973 that saw all the rolling stock renumbered and their records, such as maintenance etc., computorised.
The BR green livery both all over green and two tone green started to give way to the new corporate blue in 1966. Yellow front end warning panels also varied. Some locos had small yellow panels (SYP); others gained full yellow ends (FYE) both and either in green or blue.
Many green locos had the D painted out; others did not.
Early blue repaints kept the prefix whilst later ones did not have it. Some early blue locos later had the D painted out. Therefore from 1968 until the beginning of TOPS in 1973 locos were green or blue, with small yellow panels or full yellow ends and with or without the D prefix.
This means you can justify running plain green, two tone green locomotives running alongside blue Dxxxx numbered or even TOPS numbered locomotives especially with a little research to choose the respective numbers carefully.
