And I don't know if the points still exist, but back in the old days, before the Sunderland extension, the yellow and red lines stopped at Heworth, which necessitated the train switching track as it approached Heworth, so it could turn round.
Now, I don't know if that change over is still possible, or if there is an equivalent set of points between Heworth and Pelaw, but it there is, that might make closing one platform at a time possible.
Obviously will be more complicated when it comes to the concourse. How was that managed at Haymarket when that was completely rebuilt up top?
