I agree. And anyway it would be impractical: there are too many possible
destinations. A better target for long-distance journeys via London
would be to reduce two changes to one, by running trains across the
centre to a terminus the other side. Brussels does this, apart from
Eurostar - trains to the north start from the south station, and vice
versa.

As, indeed, does Dublin. Southbound from Connolly to Rosslare and some
northbound trains from Pearse. Unfortunately the Irish equivalent is not
quite on the same scale as Brussels!
