I was away to York earlier in the week noticed that they have started the installation of the glass panels on the steel structure (just seen the earlier posts)

The improvements are going to be great. Actually will feel like a proper terminus. Used to feel so grotty and claustrophobic. Amazed that train shed was covered for so long it was criminal.
Yes. But this is preferable to the historic option (as you see at the end of platforms 4/5 and 6/7 currently) where the buffers go straight to concrete: in that case, a train running (fast) into the buffers will get compressed and potentially telescope as it very quickly reaches something solid. This typically causes sufficient casualties that the frangible decking, even publicly accessible, is considered the lower risk option. The preferred solution, if there's space, is just to have a large overrun.This frangible decking... Does this mean that if something hits the buffers with a reasonable amount of force, then everyone milling about between the barriers and the platform end, as people tend to do in the peak, have to dive out of the way before the ground they’re on gets ripped up? Has this really been thought through properly? Looking at the pics above, the decking seems to be open to the public to walk on.
Is St Pancras international platforms an example where it’s pretty well hidden? IIRC Brighton has an older version of decked overruns behind the buffers?It is open to the public, as is the similar area at the end of the extended platforms 5 and 6 at Waverley. It is inconceivable that any overshoot would be at anything over a few mph.
AFAIK they're still fine, but they need a lot of space behind the buffers (and unlike pure friction arresting buffers they permanently need the space, so you can't put any decking there), which Queen Street doesn't have. Others will know better, though.Fair enough. I guess it is unlikely, though I’m reminded of that pacer at Lime Street in the 1980s and the track machine at Queen Street a couple of years ago, though that did happen when the station was closed. I take it hydraulic buffers as per Central are totally out of the question for new installs?
It has already been extended to take a 4 car 23m unit.
Was only planned to be exdended to allow four coaches to fit. IIRC if it was further extended it'd run into the stairs down to the low level before you even managed to get a fifth 23m coach in. I could be wrong though.Any plans to extend Platform 1? I think it was talked about years ago.
