Ended up as a sort of montage of a number of different stations rather an any one in particular, and using a huge number of reference photos to try and nail Tube look (and hopefully the vibe). Especially as not being a Londoner myself, I tried to use reference photos to add details to the vague vision of a Tube station I had in my mind. That said certain areas ended up taking more from certain locations. The platform is certainly inspired by the Jubilee Line stations and in particular Waterloo. The T-side approach is a mix of several areas in Bond Street station, the CT-spawn escalators were modelled after those in Angel Station, and the motif (and steepness) of the emergency stairs are based off Covent Garden. I don't think they were worried about stair clipping back in 1900s.
