I was bobbing around the Underground last week on the way home taking photos of this and that - mainly tiles, but that's a different thread - when I noticed at Brixton that the headwall signal had a bright RCC (or ROC, I couldn't quite make out) symbol illuminated next to it. Can anyone in the know explain what this stands for and what it means? It hasn't come up well on the photo but is visible. Route securing or the like? Something to do with stepping back?

A complete guess, Rear Cab Clear?

I am aware that the Victoria line operates 'Stepping Back' at Brixton, where one driver brings the train into the platform, and a driver already waiting at the other end boards and takes the train north. The driver who brought that train in then walks to the north end and so the process continues. This means that the turn around times in the platform can be reduced.
I would assume that this RCC, (Rear Cab Clear) indicator is the same as at Aldgate, in that it is activated on the platform to inform the new driver that the previous driver is clear of the train and it is safe to depart, (without taking a colleague with you who should be on the platform)!

A complete guess, Rear Cab Clear? For a complete guess, that's exactly what RCC stands for, (care to guess at this weeks lottery numbers? lol). The driver of an arriving train operates a plunger on the south end of either platform at Brixton once he/she has left the cab.

I don't do the lottery, but I will say Germany.
As its an indicator rather than a signal, if the signal clears and the indicator doesn't light, does the train op have to wait, or will the signal not clear until the indicator lights?
Also, what cancels it?

Also, what cancels it? In theory the train op is meant to wait until it is lit up, but in practise a lot of T/ops don't really take a lot of notice of it. Many a time a T/op has forgotten to hit the plunger at the south end for one reason or another, we don't really worry about it. It's very rare for a T/op to still be on the south end of the train when it departs and if they were, they'd hit the emergency stop button as soon as the train started moving. The starting signal and the RCC sign are independant of each other.
