The LNER Encyclopedia

Apologies for my failure to trawl the entire forum in search of a possible answer before posting this question. I admit my guilt now.

Here's the question. Does anybody know please, did the LNER, i.e. pre-1948, not BR(ER), adopt the practice of painting the faces of any former GNR disc signals yellow, to indicate that they could be passed with caution, for instance when the requirement to shunt did not involve use of a crossover that the signal was meant to protect? If the LNER did do this, did it commence at a known date post-grouping, or was it pre-group practice too?

Any pearls of definite wisdom most gratefully received.

Certainly they did - but I can't offer exact dates.

An interesting circumstance occurred at Luton where discs on running lines that would be passed at danger in certain circumstances were painted yellow. This was slightly irregular as it authorised wrong direction running (albeit short distances) which might infringe block working clearing points etc. Later, they backtracked and painted them red again. But that did not prevent yellow discs remaining at yard outlets etc which was the typical use.

Rough guestimate is that this happened in the 1930s and the 1950s respectively.
