I have to say London Euston, as someone normally used to arriving in London at the modernised splendour of Kings Cross St P, arriving into Euston the other week at the very dull 1960's built Euston was a bit of a shock, it doesn't seem to have changed much since the last time I was there which is probably about 20 years ago. Add to which the vastly superior range of connections offered at KX with Thameslink, High Speed Kent services and Eurostar, one wonders how many passengers like myself from Leeds would prefer the East Coast service than the HS2 destination of Euston.
As for a Scary station Bradford and Wakefield Kirkgate, although the station itself now looks better after partial refurb, I'm sure it will look great after a full refurb.
