I'd thought that the only new work (aside from resignalling and re-

Vallance Road, with the line from Whitechapel to Vallance Road taking
the same route as before...

If the work is at the north end of the platforms it's the Crossrail
interchange subways, which the board papers (or some similar document)
say are being put in during the current closure.

The Crossrail platforms will be to the north of the District Line.
