Re: I'd go further
Not TfL but BR.
I used to commute into Marylebone (the unforgiveable performance of the Chiltern line would deserve a post of its own).
The whole station was painted. They did a really good job. They even picket out all the little details of the frieze of the news kiosk.
When that was finished they sandblasted the brickwork getting dust over the new paintwork.
Then they filled in the track of the north platform covering the lower part of the newly sandblasted wall.
Then they replaced the track by digging out a new one down the middle of the wide platform that, in the previous days had allowed vehicles to drive onto it if it was useful to transfer stuff onto a train, cutting off that as a future opeion.
Then they reorganised the forecourt, demolishing the old three-sided open kiosk that enabled one to buy a paper on the way to or from the platforms almost without breaking stride) and replacing it with one in an out of the way little cubby hole.
