I do hope they work out how Signalling works.
I cant think of any situation where a Distant would be higher than a Home.
Though there are situations with double Distants. Indeed in the Birmingham area there were signal posts with up to three distant signals, essentially providing four aspect semaphore signalling! With an Outer Distant, Middle Distant and Inner Distant signal provided!
So you got
Code:
Box A Box B Box C Box D Box E
G G G G R
G G G Y Y
G G Y Y Y
G Y Y Y Y
the Great Western were funny little buggers at times!
(G = Green, Y = Yellow, R = Red)
And in four aspect signalling that would be,
Green
Green
Double Yellow
Yellow
Red
It can be confusing, cant it.
