So, with plenty of spare time at weekends, I have been catching up with some research. This however has thrown up a quandary. Vacuum pipe ends for BR Stock Red - Fitted White - Through Piped. That's the standard and that's what we follow. Correct? I received on Saturday BR.87209 dated December 1958 this being "Naming, lettering and telegraph coding of freight rolling stock, including containers, wagon sheets and ropes - Identification markings and painted colours of freight rolling stock, including containers and wagon sheets." On page 23 this states: "On fitted stock, the vacuum pipe to be painted bauxite red from headstock to rubber connection and on piped only stock to be white from headstock to rubber connection" This started the cogs turning. BR11883 Regulations for Repairing Wagons March 1970 states Red and all current regulations that mention vacuum brakes state the same. BR9210 The repainting treatment of repaired freight stock and containers, including breakdown train vehicles and other service stock January 1963 agrees with the December 1958 BR87209 however the Automatic Vacuum Brake manual issued January 1967 states Red. So between December 1958 until January 1963 I have written standards that state fitted vacuum vehicles require Bauxite vacuum pipes, not Red. LNER and GWR practice was Black - Fitted (a Red V on fitted GWR stock) Red - Through piped So my questions/thoughts, more for interest/something to do during this lockdown. Did the marking of fitted vehicle pipes in any other colour that black happen before BR in 1948? Did the marking of fitted vehicle pipes in bauxite happen before the documented standard of December 1958? When between January 1963 - January 1967 did red become the standard?
