Probably quicker. Plus it would have the added benefit of taking a
large number of passengers off the already way overcrowded northern
bank branch line - though to be really effective it would have to go
to as far as east finchley as most people probably couldn't be arsed
to climb up at highgate to get to the high level station but just
hopping across the platform at east finchley (especially if they're
likely to get a seat) would be much more attractive.
