And, while I'm in obvious (but not to me) question mode, above the
signals are larger ones that occasionally display U B in two boxes.
Why?
They are telling the driver which route he's going to take (so he
knows which speed restrictions apply and which is the next signal to
obey). Normally I would suggest it's short for "Up Bolton", but
Quail tells me that all directions from Man Vic are Down, and
there's no Bolton line leaving the station.
["U" is normally "Up". Going "wrong road" is normally shown with an
"X".]
No, it's definitely not Bolton. The indicators are on the eastbound
signals.
I can't help you on that one, either. According to Quail, the eastbound
lines are Up/Down Rochdale Fast/Slow. I haven't got an old Quail to hand
but, pre-Metrolink, the Bury lines might have been Up/Down Bury - these days
they are simply known as Inbound and Outbound and are not governed by the
same signalling system, in any case.
