Just been looking at at these telegraphic codes that the railways used to use & some forum members too it would seem. When did these stop being used in day to day messages? - the listings on the website are from a 1980s BR publication. Looking at the full listing available at railwaycodes.org.uk some appear quite obvious but most are obscure & have little resemblance to there actual meaning. Did staff actually have conversations amongst themselves using such lingo!!
