Alright, clickbaity title, but when the extension opens it will be in
Zone 1, and Kennington which is currently in Zone 2 will become a Zone
1/2 boundary station, so that London-Kennington journeys will become
cheaper than now. Since people in the vicinity of the new stations are
presumably using Zone 1/2 station Vauxhall at the moment, TfL won't be
getting much extra revenue from them, so maybe TfL total revenue will go
down when the new stations open.
