From 2018, it will again be possible to travel from Farringdon to
Finsbury Park, as that route is one of the extensions being implemented
in the Thameslink Programme. Trains will run via St Pancras
International, and then by a new link to the ECML.

Now, that is interesting. I wonder what the route will be.

The redevelopment of St Pancras included a new link from just north of
the new Thameslink platforms to the ECML. The tunnels are complete, but
may not have any track in them yet. It's two single-track bored tunnels
for most of the way, then a short section of double-track cut-and-cover,
emerging into a concrete-walled cutting. You can see the cutting on
Google's satellite view immediately south of the western end of the
covered bridge that carries HighSpeed 1 over the ECML.
