on those that I've seen don't switch off - due, say, to a fault - the projected beam goes onto the roof of the train and doesn't get in anyone's way. Unless there's some over-riding need (say to do with air time for the adverts), I'd vote for leaving them on. I certainly can't see how they'd distract the T/op of an approaching trains!

The reason they switch off is because it's considered unsafe having passengers' attention focussed on the adverts as a train is approaching.

Maybe barriers should be erected at the platform edge in the areas that face directly on to one of the projection screens, lest anyone gets so 'drawn in' to the advert that they continue to step closer and closer towards it and off the edge.

Once the JNUP is finished, and the trains have to dock at pre-defined positions - and hence the doors, couldn't barriers be put up along the platform edges except for where the doors will be?

What if the driver overuns by a few inches when driving manually? The doors will open onto a barrier

Doesn't seem to matter on the Jubbly, does it?

Anyway, I hate the moving posters on escalators, they give me a sense of vertigo.

Thanks Angel! You said both of the things I was going to say, and did it for me so I don't have to!

Once the JNUP project is finished trains should always dock properly except for the odd time when the're a c. 1ft under- or over-run, which wouldn't pose a problem.

I always start to trip if one of those damn "scrolling" posters sets off just as I'm walking up to/past it, because I instinctively aim to put my next foot down 1 foot lower than before, because I feel as if the ground is suddenly 1 foot lower than it is. No matter how hard I try to psyche myself into not getting fooled by this, my instincts override the logic every time.

Personally I don't mind the scrolling LCD screens but I can see how they could be distracting. I don't like the projected adverts on the tunnel wall though. For starters the colour/contrast is all wrong and the huge projector enclosures are hideous. I don't know the specifics of these particular projectors but I think you'll find the projector is much smaller than the box. I would guess the boxes are partly to keep the projectors clean as they don't like getting dirty and would fail quite quickly without some sort of protection. Obviously you can't seal something like a projector in an air tight box without some other form of cooling which must be integrated into the box.... hence the big box.

It will be interesting to see how often the lamps get changed too. Projectors tend to get a bit dim as the lamp ages so it will be interesting to see what the criteria for re-lamping is.

The station Adverts can be a real pain as contractors turn up to do "resets" because the bulbs overheat, & also the "timing section" that is supposed to turn them on/off as the train approaches/departs often fails,
As a word of caution CBS who do the adverts are looking at how to do adverts in the tunnel !! this is for customers to see as they travel between stations !!!!
How this would effect T/Ops is anybodys guess, let alone the logistics of installation.

I seem to remember something like this being proposed in the '70s....perhaps on "Tomorrow's World"......the idea being that a series of still images,on the tunnel wall,would appear to move,like stop-frame animation,as the train passed through.
It always seemd implausible to me,for reasons I could never quite put my finger on.
Was it ever trialled?
Does anyone else remember this?

I do remember this - about 1985?

I think it was/is operational somewhere in continental Europe. I'm heading out now, but will have a search tomorrow and post if I find anything.

Perhaps I should clarify that by "scrolling" adverts I don't mean the LCD screens. They give me no problem at all. I mean the ones where two adverts are printed on a paper strip, which is wound round every few seconds by a good old-fashioned motor.

It's been discussed elsewhere on the forum, but I remember seeing animated adverts (it looked like LEDs) in the S-bahn tunnel between Frankfurt Airport and Frankfurt city centre. The advert I saw was of a stick man running along side the train, I think it was for Addidas or some brand like that. It was rather cleverly done.

If this is the same way that CBS are thinking of doing it in London then it should in theory be possible for the timing to be such that the t/ops never see it switched on while driving.

I'd have thought that the large amount of cabling in the tunnels, frequently at about window level, would provide too great a logistical obstacle to something like this being installed.

CBS have been putting in a lot of fibre optic cable lately, which runs from station to station, I believe the "intention" is to install mini cameras that beam light back into the tunnel rings giving the appearance of images, if it works then CBS will get approx 50k per side per section ! (who said theres no money about ?)

I really don't mind them - and apparently they are greener than the alternative of paper posters wihch need to be transported in lorries etc. in the long run. They are pretty damn big though; I'm sure that could be refined.

There was a tunnel installation in the Heathrow Express tunnels. Was marginally impressive when I first saw it. And then just annoying.
