"Not much of a hardship unless they're really far away."
They're as far away as you can get and still be in the station.
Agree in principle, not a *huge* hardship, but given pressures of finding available racks and hoofing it back up to the trains (along with general pressure of catching train), I can only see this encouraging people to cycle (or run with bike) thru station and generating conflict.
I don't think it's been well thought through. In fact, I *know* its not been well thought through, because the person responsible seemed baffled when I raised it. It simply had not occurred to them that there was any problem at all in closing south rank to bikes.
Anyone want to do a demo before Monday - one riding on south ramp, locking bike and coming back to barriers to catch train v. north ramp, walking through station and back again? might help generate pressure for the new racks that chdot was talking about.
