Kings Cross is not a “new station”
According to HS2’s Rupert Walker, “the redevelopment at Kings Cross has shown us what you can do with a new station”.
But Kings Cross is not a ‘new station’. In March 2012 a new concourse — structurally independent of the station itself — replaced the 1970s one. Apart from the commissioning of ‘platform 0’, relatively little of the station has changed. What did change, was the area around the station.
There is no valid comparison to be made between the development at Kings Cross, and the proposed rebuild of Euston for HS2.
