What were platforms 20-24 used for before construction of the Eurostar
terminal? They looked forlorn and neglected the only time I remember
seeing them in the late eighties. Was there a canopy that was
demolished to make way for Eurostar?

There were only 2 platforms, 20 and 21. There were also some sidings and
the lift used for access to the Waterloo and City Line.
