Rebuilding of White Hart Lane

Fronts onto an embankment...that's quite common. St James St on the Chingford branch, built at much the same time, is exactly similar.

Waysider.

The 'new build' is in fact South of the present station on the up side
I cannot remember any second stairway on the up side at all in all my years of using the station. However there was a second stairway on the down platform which was about halfway along and exited alongside the original stairs onto White Hart Lane and was used only during Spurs home matches.
I also understand that there was talk at one point that there was going to be a aerial walkway from the ground to the station going over Tottenham high road,but it looks from the plans and drawing that is now dropped

Northbound!!!! Yes i never knew why they were taken out as thre trains were quite wedged and splitting the exit groups halfway along cleared the platforms a bit quicker. Now there are instances where the rear of the last trains occupants havent got to the exit and are then added to by the next train emptying. god knows how they are going to cope when the capacity doubles next year
I just hope that someone suddenly wakes up and gets the soutbound Stansteds to stop at Park. They do it on some northbound before the game but it is going to be chaos for a few months until everything is organised. My son is absolutely spitting feathers as the opportunity is there at WHL to add a bay on the london side so at least a shuttle of some short could be run, if only down to seven sisters and back in between the rather laughable service they put on now.
When the service was first introduced waaaay back in Nov 60 there were 9 trains an hour from Lower Edmonton, 0.20.40 fast to L Street
3.23 34 all station stoppers,13.33.53 all stations to Hackney downs then fast to LS. Surely it it not beyond the wit of man to get something like than put in for an hour or so after the game to clear the crowd. I always thought that LUL could have put an island platform in at Park to take a lot of the crowd straight onto the Vic line. With the re installation of the four track, eventually, it could still be done. We are lagging well behind the German system such as Bayern Munich and other stadia where trains appear out of nowhere to shift the crowds. Still no doubt some pessimist old b*gger will say it cant be done due to elfnsafty and lack of platforms.at LS

Is this wishful thinking. In 2016 it was estimated the cost to Spurs of 12 million and there is a petition to stop the renaming.

The costs associated with changing a station name will include:
Changing all the signage at the station
Changing all the signage at other stations on the route to reflect the new name
Changing DMIs at stations and on trains
Recording new audio announcements for trains and stations, and updating the existing ones.
Changing maps and other publicity
Changing signalling diagrams (and possibly other bits of signalling kit), sectional diagrams, etc.
Publicity about the name change
Making sure all the emergency services in the area formally know of the name change

and probably several things I haven't thought of, but I can't say whether all this totals £12m (a figure which this news article attributes to TfL)

For a London Overground station Network Rail will have to bear many of these costs, and presumably TfL would have to pay NR if they want to change a name. Network Rail were quoted as saying that renaming Blackfriars station was not financially justifiable "in this age of austerity" but I can't find any actual figures quoted after a short google.

When the new entrance on the south side of the river opened, people wanted the name of the station to reflect that although there wasn't (AFIAK) a consensus on what the new name should be constructions like "Blackfriars and Bankside" or "Blackfriars and South Bank" were suggested. There was no proposal to rename the tube station that I'm aware of.
