My train to London Kings Cross has just been cancelled, so instead of having plenty of time to make a connection to Euston, I'm going to have a mad dash...
To get from Kings Cross to Euston I have a number of options, but given that my train ticket includes an Underground journey, I'm thinking that either walking (fast!) or tube would be my best bet. Given the tight connection, I'm after the fastest way to do it. What would that be?
Based on this 3D model of Kings Cross / St Pancras underground station, I see that none of the underground lines are that close to the Northern Ticket hall where my later train will come into. At the Euston end, I know that Euston Square station is quite a fair way from Euston station itself, which the Victoria or Northern Lines are quite deep so there'd be walking + escalators to get up to the surface (plus the long walk+escalator at the KX end to get to them). Walking wise, not sure which is the quickest way to go, but I suspect it wouldn't necessarily be the "obvious" one along Euston Road.
So, which is the quickest way - tube (if so which) or fast walk (if so which way)?
