I'd like to travel from Finsbury Park to Shelford (Cambridgeshire).
There are two obvious routes: (1) train to Cambridge and then train to
Shelford; (2) Tube to Tottenham Hale and then train to Shelford.

There's another one that's only slightly fruitcake:
Finsbury Park to Hertford North
walk to Hertford East
Hertford East to Broxbourne
Broxbourne to Shelford

I wonder what the routing would make of that?
