Sorry Mickey; despite my lengthy description, I now realise that I only generally referred to that whole signal as a 'structure' : Rather than being a gantry, it was actually a 3-doll bracket affair that carried the five arms, with the two dolls for the Up Slow on the lower, left-hand, bracket, and the two UF arms' doll on the higher, right-hand bracket : A slightly strange looking arrangement really.Mickey wrote: ↑Thu May 25, 2017 12:43 amYes I have seen a distant shot of those signals on that gantry from a few photographs in the past Stevie but I never saw it in real life it was several years before my time, the first time that I travelled through New Southgate on a train was around June/July 1967 and I don't recall that gantry still being there at that time.

I think it probably had gone by 1967, as I never saw it either.
There may be some other signalling interest in that the replacement colour-light UF starter (No.16) was the only signal I ever knowingly encountered which was released by the "Line Clear - One Train" arrangement instead of the common "Line Clear - One Pull'.
This meant that you could clear it and put it back to Danger as many times as you wanted while 'the Block' was at 'Line Clear' - provided that the signal's approach track circuit, which started just clear of the US-UF crossover, was indicating Clear.
Once that TC was occupied, you could only clear the starter once if it was at red at the time, or if it was already 'Off' you wouldn't be able to pull it again if you put it back while the TC was occupied.
Incidentally that TC going Clear when a train cleared its south end going towards the tunnel was arranged electrically to 'Last Wheel Replace' the signal to Danger even if its lever was still Reverse.
giner , Pretty sure that I never saw anything on that narrow gauge line either.
If I'd been braver then and gone through the always open dilapidated gate over the line, I'd have found for sure where it led to (and probably sketched the route and layout).
[ Apologies to all, on realising that we've wandered some way on here from "Park Siding....", (though less than 1 mile geographically ! ).]
