Surely it'd be better to transfer from the Met to Thamelink at
Farringdon anyway, as it's just over the footbridge rather than a long
walk.

Good point actually! The OP mentioned KX so I just ran with it without
thinking. Either way, though, it's a slow and miserable journey going via
Thameslink.

TBH, if I was going from Harrow with luggage then I'd go to Harrow and
Wealdstone and get a (Southern) Watford - Gatwick - Brighton train right
through, without any changes at all.
