During the meet last Saturday I remember telling someone that I once saw DD's favourite signal at Hanger Lane Junction at danger but with the 'arbour lights' displayed as well.
Since then I have been trying to suss out how that is possible as I always was told it wasn't.
Can one of a signal dept members offer an explanation?

What you saw might have been part of the following:
- the programme machine in WM IMR calls WM20 (rte 1)
- No.20 lever is rotated to reverse
- the points move and lock
- the arbor lights are proved and illuminated
(here is where the observer comes in)
- the signal is proved and puffed off, illuminating the green aspect
- the trainstop starts lowering
- the trainstop fully lowers
- the red aspect is extinguished and the route is ready for the train
Needs more BAET, explaining how fast WM IMR works...

No, no the Signal was RED withe the 'arbour lights lit too. There was a Piccadilly train standing at it with the driver on the phone.

Selection path is all good to feed the route lights... if 3 lights there is sufficient current to energise the UECR but it doesn't pick up OR the UECR is up but the GR isn't. (Either relay defective...)
If less than six filaments lit UECR has insufficient current to energise.

Oh. That's brokenness then, IMHO...
