Today St Pancras is both the Eurostar terminal for services to Paris, Brussels and Amsterdam and fulfils it's traditional role serving the East Midlands and South Yorkshire.
@Maersk.146, some years back the BBC? made a documentary series that covered the restoration of St Pancras. It’s called the £800m pound station. https://www.bbc.co.uk/programmes/b008g3rl
@Kempy72 - Thanks, though it appears that BBC is no longer making the series available on the site as listed. Looks interesting, if one could see it...
