Regarding the Walthamstow Central upgrade, my assumption is that the brick wall that was buit on the platform side can quickly be dismantled. Logic tells me that as soon as this happens then all three gatelines would be brought into operation and the old gateline at the top of the escalators removed. I sure this would happen sooner than later.
I made this comment back in August regarding Walthamstow so have now been proved wrong! I think it was mentioned the the new gates will not be brought into operation until the escalator refurb is completed, my question is, that during the blockade why didn't they knock down the brick wall that forces people out of the station and back in via the station square to the Victoria line staircase? after all the old entrance to the staircase is under the platform canopy and most people alighting from the overground train could avoid getting wet but with the onset of winter all the passengers will have to troop out of the station and back in again.
