According to the stats on the 'Corporate' section of the TfL website
(
http://tinyurl.com/3y56uo), King's Cross St Pancras tube station
handled 52.51 million passengers in 2006. This sounds like a lot, but
just for comparison it handled 71.503 million passengers in 2005 (and
77.564 million in 2004, which is its outright peak).
At first the 2006 figures took me by surprise, especially because very
few tube stations suffered from a fall in patronage from 2005 to 2006,
and the fall in patronage at KXSP was virtually the equivalent of wiping
Brixton tube station off the map. Having spoken to TfL agents recently
it turns out that until recently the patronage figures for KXSP were
artifically inflated - apparently you were recorded twice if you made a
deep-level - sub-surface interchange at KXSP, until of course
paid-side interchange routes were opened in October 2006.
Goodness knows how 'low' the recorded patronage at KXSP will be this year.
