Wasn't it Charing Cross that Abercrombie wanted to abolish?

According to the map of the proposals, the line from London Bridge to
Charing Cross would have gone, along with the Thames bridges into Cannon
Street, Blackfriars and Charing Cross. However, all three would have
survived as deep-level through stations on the southern loop.

(I can't see any sign in the plan of Waterloo being demolished.)
