Hey all,
I was at West Ken tonight and noticed that the Platform Repeater for the wrong road starter signal WC9 as dark (as in, not displaying ANY aspect) whilst WC9 itself was as usual at danger. Anyone else notice this? Any reason why this is the case?
It then occurred to me, why isn't WC9 "approach lit" like the wrong road starter at Northwood?
Hope you are all well!

Light bulb has probably blown.
As for making WC9 approach lit, I dunno what the arrangements are at Northwood but this isn't possible at West Kensington as trains can reverse in the platform by pulling forward past the normal eastbound station starter (WB34) to the limit of shunt; driver then changes ends to accept WC9.

It will be a blown LED we don’t use lamps no more in platform repeaters. Please don’t shout it out to much or it will be another job for us to do.
Platform Repeaters are usually not surpressed in any way

Also it clears when trains come out of Lillie Bridge that end usually before the depot outlet clears to make sure the train will complete the move and not lock up the site incase WC9 fails usually down to the points failing when that happens |

Light bulb has probably blown. Does the signalling system allow a failed bulb/LED to be remotely detected, and reported to the signaller/maintenance teams, or does it rely on train crew or other staff reporting it? |

No lamp proving is provided except for junction indicators as trainstops / ATP will enforce a dark signal

Do tell more
If it’s a tunnel signal out of the 3 lamps 2 of them must be alight
If it’s a outside (full size) signal then out of the 6 filaments 3 of them must be alight for it to pick up the relay that will clear the signal
Our assurance team will not approve LED’s for these even though I’ve proved it will work with a small mod

No just a change to the setting of the proving unit
