Looming in the distance at Shoreditch on the ex-BR side is a sort of
signal box type cabin high up with a concrete structure beside it. I
was told this is the remains of a wagon hoist? Anyone know more about
it?

It was a signal box. The entire viaduct was built for the Bishopsgate
terminus before Liverpool Street took over that role. Bishopsgate then
became a major goods station.
