Anyone know what the major drilling, piling and concreting work is
that TfL are doing on the ELL platforms at Whitechapel station?

I'd thought that the only new work (aside from resignalling and re-
electrifying) taking place on the northern extension was west of
Vallance Road, with the line from Whitechapel to Vallance Road taking
the same route as before...
