Other ATO lines on the tube have a blue or white light for proceed in ATO

know if there's a particular reason for this?
On other systems I've read about, green means clear to the next colour
light signal whereas white/blue means that you can start under ATP,
either ATO or manual, but the line isn't clear all the way to the
next. Perhaps those signals are 3-aspect? Does anyone have a good
reference for the Victoria signalling?
Richard.
Green - All trains clear
Blue - Trains under code clear
Red - Stop and stay
All I can say is I've never seen a blue aspect on the victoria line. What
signals remain seem to go straight from red to green in my experience.
However perhaps thats just station starters and the blue signals are in the
tunnels?

There are blue and white signals at the end of the platforms, you can probably only see them from the cab. I had a cab ride a couple of weeks back and did notice the odd green signal in between stations as well, but I think they were mainly near reversing points. Trains do move towards block marker boards, which are red and white in colour.
Come to think maybe the red and green are for engineers trains, would doubt they would have the ATO equipment fitted.
