So at open air stations where there is one platform but two tracks, like Woodford with the siding platform, you'd have to make sure you pressed the right ESB, because if you pressed the one for the opposite platform nothing would happen?

I was at Woodford yesterday and noticed an emergency train stop plunger had a red light lit up underneath it, but trains seemed to be coming and leaving the station normally.
The Supervisor went up to the plunger with the red light but couldn't reset it. Then he checked all the other plungers up the platform and found one at the far end had been activated; when he reset it the red light went off.
It made me wonder how they work. The one which had been pressed was on the siding platform side.
If there was somebody on the track, but no train in the platform, would it stop a train from entering the area (but only on one track)? So if a train had tried to go into the siding platform at Woodford, would it have been stopped?
If that is the case, does it mean the train could be approaching Woodford normally and enter the next section and suddenly be sent an emergency stop signal? Or is it sophisticated enough to tell the train to slow down at a normal rate and not enter the next section? Is the driver allowed to move if s/he can't see any obstruction, or must they wait for the plunger to be reset before they can proceed?

It's an electrical 'ziggy-zaggy' hazard symbol, which is bright white. It caught my eye because when you face the tunnel entrance I could see two lights - the signal, and the one on this funny black box attached to the side of the tunnel wall.
There is also one Southbound at Tufnell Park, and yellow clips/wires coming out of the current rails which I think might be connected to it?

I noticed recently at a few Northern Line stations 'boxes' on the side of the tunnel entrance wall with a white light (I think an electrical symbol lit up).
There is one at Euston Southbound Northern Line Charing X branch.
Are these new? I guessed they might have something to do with the traction current?

When there was a problem with brakes on the Northern Line back in October 2005 is it through a Tripcock Tester(s) that the problem was discovered?

Isn't it if the light stays on you've failed the tripcock test??? I think thats what aetearlscourt is saying (the driver should notice [that the light has remained on...]) Fig. three on this website show's one: www.trainweb.org/tubeprune/Signalling%20photos.htmBut Tubeprune says that the light can be 'white, blue or purple, depending on location'.

The blue platform end lights on the JLE are to confirm that the PEDs are closed. no, it's not those ones... because Canning Town is above ground so there are no PEDs... It's a circular lamp that comes on as the train is approaching the stop mark but then goes off again.

I noticed today at Euston Square that as the train toward Baker Street entered the station, a bluish purple light came on on the tunnel wall at the end of the platform above the signal. I noticed a similar light at Canning Town on the Jubilee Line - can anybody explain what it is?
(I tried to search to see if the question had been answered before and couldn't find anything...)

"DISTRICT LINE: Severe delays between Barking and Upminster due to a dog on the track at Upney.
Message received 6:53pm"
Does it happen very often? I can imagine some poor people chasing a dog up the tracks in the dark... Have any other animals ever found there way onto the tracks, causing delays to the service?

I agree that people want to travel from a --> b as quickly and safely as possible. It is important for the stations to be clean, for all the lights to be working etc.
At Roding Valley, IMO, not a great deal came out of the refurbishment for customers: the help points are unanswered and still have stickers on them saying "information is not currently available from this help point". The ticket office is never open. The toilets are always locked and were unlikely ever to be used in the first place - placed outside the platform, at the foot of the bridge near a small secluded cul-de-sac. It looks nice, but not that different to how it was before from the customers point of view, and must have cost a fortune.
Refurbishing the stations isn't a bad thing in itself but the cost of it seems out of proportion to the benefits at some stations.

I was thinking this morning... From my point of view, as a regular customer, there has been a lot of activity lately - lots of stations have been refurbished - e.g. Roding Valley, Woodford, South Woodford, Snaresbrook etc. and there is 'activity' on almost all areas of the network.
If Metronet did go bust, what would happen to all these works-in-progress?

I think we should wait and see what happens first!
