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?
Surely they were being built in the late 80s? Actually, I think they
were built earlier - early 80s - but the construction of the Channel
Tunnel was delayed so that they did sit mothballed for awhile.
