In particular, the underground platforms at Manchester Victoria, as well as Leeds.
Glasgow Queen Street Low Level - depressing, draughty & drab.
I'd say they're okay, but the fact that they have no doors makes it cold.Merseyrail yellow shelter design is so bad you’re usually better off standing outside, even if you’re at the top of an embankment. Big gaps at the top and bottom turn them into wind tunnels specifically designed to chill your ankles and face.
The Cumbrian Coast stations which are alongside the sea can be extremely draughty on a windy day - Seascale, Sellafield, Braystones and Nethertown.
They would get my vote for very draughtyPlatforms 13/14 at Manchester Piccadilly or Manchester oxford road
Preston on a windy night
I can remember a few freezing cold hours 'in' Darlington station when hunting Pacers in 2017/2018 when they were on borrowed time.
