All the London railway stations :
I visited Swiss Cottage in July 2019. What an awfully inaccessible station. Lots and lots of stairs, and escalators
Underground lines : Jubilee
Swiss Cottage station - what lies below?
Step free access between north and south platforms - I would recommend travel south, past Baker street
Swiss Cottage station escalator from platform
Swiss Cottage station between escalator and exit, note the stairs
Swiss Cottage station, more stairs
Swiss Cottage station, even more stairs
Accessibility friendly : Swiss Cottage is not accessible to wheelchair users due to 60 stairs or escalators between the platform and street level.
