That's the price of progress, of course: before they plonked the
shopping centre in St.Pancras you could easily change from Picc line to
Thameslink in under 3 minutes using the now abandoned station.

The change they made was moving the Thameslink station. It's as far
south as it could be now, given the curvature of the tunnels. The whole
thing's a mess, frankly. Perhaps the entrance to the new Thameslink
station could have been close by the Eurostar check-in, rather than
halfway to Camden.
