Hi Peter,
Regarding 'Co-Actor' Signals.
I have extracted this from an LU standard-
"When a passenger train is berthed at the defined platform stopping point, the train operator shall have clear visibility of the signal or co-actor whilst:
a) Monitoring the safe closing of the doors;
b) Looking forward, from the normal driving position, in the direction of travel."
Co-actors are generally not favoured by operators and maintainers. They tend to clutter the platform areas. However, there are some situations where only 'co-actor' signals can resolve the signal sighting issues. 'co-actors' may be placed on the otherside of the main signal, on a gantry in the front (further donw), sideways on a tight tunnel wall, etc.
Obtaining approval from Train Operators, H & S representatives and Signal Sighting Committee is the deciding task.
Hope this provides some insight. I will look out for more information and post here. I was having problems with the attachment above, I will upload again.
Regards
Aditi
