Is there a particular reason why over the past year or two some LUL signals have gained blue and white surrounds instead of the usual black?
RJB1 and JB1 on the approach to Harrow on the Hill spring to mind.
Is LUL copying the NR practice of making SPAD prone signals more prominent?

Yes, that's exactly the reason.

Yes, that's exactly the reason. Many thanks I do find it interesting that LUL have applied the blue and white surround to RJB1, a repeater signal. AFAIK this isn't done on NR. |

NR tend to have fewer repeaters in the same style as LU.
However, I most confess that I don't agree with blue and white reflective stripes, in clear skies they blend into the sky and in darkness they just reflect your (ultra-bright) headlights back, risking dazzle.
Signals with a poor SPAD history need to be carefully analysed for time and weather conditions, and in a lot of cases to make them stand out better needs a bigger black sighting board - not a knee-jerk application of the 'pharaoh' stripes.

White back plates were reserved for signals that were not normally illuminated ie; fog repeaters and rail gap indicators. This was so the driver did not treat them as a signal with no aspect and a danger signal.

Though there's only so much of the sky and the sun that one can afford to black out! |
