With the release of Walsall, something I spotted on one of Soi Buakhao's videos... https://youtu.be/VSAAewosATM?t=285 Watch the signal (WL26??) as the 20 trundles past... Any ideas why that happened??! Last edited: 03/08/2024 at 12:25 by 304033 Reason: None given Log in to reply |

There could be any number of things that *could* cause that to happen, but I could not tell you for sure what did cause it.

It looks like that signal is not on the route that the 20 is taking. So my guess would be that the movement of the track is somehow shaking a wire connection (one of the one that bridges rail joints) just enough to break the circuit momentarily and cause the other signal to go back to red; it then remakes, so the signal steps back up to the correct aspect. But just a guess. Log in to reply The following user said thank you: 304033 |

The original 1965 signalling notice for Walsall is publically available from SRS website. https://www.s-r-s.org.uk/archivesignals/brmr.php Both WL25 and WL26 are the same format and had route 'G' for Wednesbury - which seems to be where the 20 goes. So I think it is WL26 and applies to the train. WL25 is visible in the still frame at 4:40, and is lower down Log in to reply The following user said thank you: 304033 |

I would suggest that the detection of the points the freight is traversing might be a bit “light”, or the track through the points is not in the best condition and excessive movement is breaking the detection briefly as the loco traverses the points. The points are probably proved in that position to enable that signal to clear. When the detection is briefly lost, the signal returns to stop. The track circuit past the signal does not drop, so the signal re-clears when detection is restored without the signal needing to be re-stroked. There could be other scenarios, but that’s where I’d start looking. Log in to reply The following user said thank you: 304033 |
