Are you sure about 'equally'? I've always found it far easier to get
on the NCL at Finsbury Park at 0830 than, say, the Northern Line at
Kentish Town at the same time. The full-size trains seems to have a
significantly larger passenger capacity (which would be further
increased if the 2x3 seating were replaced with 2x2 wide-aisle, as in
SWT's 455s).
