Overall I'm really disappointed by the new London Bridge station, while yes it's very impressive engineering there just seem to be so many things which could have been designed better, or have just been badly done.
The design itself seems odd. In the past the high level platforms felt like an afterthought, with terrible access via the long ramps or the grotty overbridge, with the southern side having a proper concourse. Now it feels the other way around. The high level platforms have four escalators and a lift for each island platform, with a wide (but very long) staircase too. The low level has a strange
arrangement of 2 island platforms and 2 single platforms, with the 2 island platforms (10 and 15) being far too narrow. In the peaks staff routinely have to use barriers for crowd control and allow trains to unload before allowing people on the platform. The sheep pen in front of platform 15 may have finally gone, but even with all the hoardings gone it's really not much better.
The access to the lower concourse from the high level platforms is very poor, single escalators always running up (understandably), and a single lift for 6 platforms.
The staff only lift with the security guard to prevent non-staff using it is frankly ridiculous.
I wonder if it would have been possible to arrange the 6 low level platforms as 3 sets of island platforms, which would have reduced the narrow platform problem a bit, although perhaps the signal box at the end of platform 15 would prevent that. Although having said that, the publicity said that while platform 15 was only 10 carriages long, there was provision for it to be lengthened if the signal box was ever moved. When spending billions on the project why not move it as part of the work? It seems to be the only thing from the old station that's been retained.
The space lost at platform level by having the full length of the escalators uncovered doesn't help either. I imagine this was to increase the natural light on the lower concourse but the lower concourse is so big that most of the lighting there is artificial anyway, and the ceilings so high that it being more closed wouldn't automatically turn it into anything like Birmingham New Street.
The location of the ticket office isn't obvious whichever entrance you come in by, and the lack of any ticket office or even machines on the bus station concourse for platforms 10-15 is crazy. There are temporary machines where
the entrance for the old platforms 1-6 was, but this is another really unclear location - there's no reason for passengers to walk down there any more. Why couldn't a few machines be placed on the concourse?
There is however good provision of payphones - I don't think I've ever seen one used, unsurprisingly these days.
The ticket barrier and departure board positioning is odd. The staggered barrier line on 10-15 is a relic of an emergency change after the severe overcrowding problems when they first opened, and is just strange now. I don't see how it could be changed now though - the shops on the right take up too much concourse space. The lower concourse departure boards for 10-15 mean people stand in front of the escalators up blocking access to them. It's awkward at the best of times but with a minor amount of disruption it becomes chaotic, with people turning when their train is announced into the other facing the other way.
Then there's the detail of the actual work on top of the design. There's lots of things unfinished (I know the station itself is unfinished but these are things in the completed part, with no sign of anyone ever coming to finish them off). Things like incomplete wood panelling, trim incomplete or falling off around escalators etc - many of the escalator panels have pieces of foam or gaffer tape inbetween them.
Things that were needed for day to day operation were clearly not in the design, for example there are storage places for wheelchair ramps in the platform structures but these have since been added to with makeshift looking ones at other places on the platforms, usually with hazard warning tape around them. For a brand new station there's a remarkable amount of warning tape around the place.
As a rare positive point though, the next train display boards showing the next 3 trains are an excellent design.
Phew. That was longer than I expected!
In short, it feels like it could have been a fantastic station, but really just isn't and is big and impressive yet also very mediocre.
