BTW - did you know that the original signal aspects on main line railways
were white for clear and red for stop or caution (distants were not well
differentiated in the early days). I do not know when the green aspect
became the standard, but suspect that it was in the early years of the
twentieth century as electric lighting external to the railway became
common.

Green used to be the caution aspect:

White is right and red is wrong.
Green means gently go along.

My memory says it was around WW1 that the caution aspect moved to
yellow, allowing green to mean clear.

On the big railway, shunters' handlamps show white for go and green for
slow down.

Nothing. In fac rumour has it that the white aspects are going to
be replaced with blue aspects, to match the blue aspects to be
used on the VLU signalling.

Buuut...If you do that, then they could be confused with lamps
associated with tripcock testers. Fun eh?

Other than white is also a valid TCT colour too , depending on the
location.

Bloody hell, yet another TLA. Whats TCT then?

Ahem, as sir will note above, a Tripcock Tester?

But surely that should be TT?

It may be worth pointing out that there are no tripcocks on the central line
(or the vic line).

There is one on the Victoria Line, at signal VK11.

That would be a trainstop, surely?

I remember at conversation like this at the RTC in the 1970s ("Railway
Training Centre", before anyone asks...)....someone suggested using a
black light.....
