I get the impression that both BRILL/R - BYLINES send a collection of old photographs on a subject to certain individuals to write notes & captions on the subject matter.
While these people probably know an fair bit in general about UK railway subjects - it's a completely different ball game over this side of the Irish Sea.
The northend of WOODBROOK DART station is where this photo was taken from [ S/JUNC S/BOX - from NLI -O'DEA COLLECTION]
