Someone will note that a passenger gets railway assistance to get from their seat at the end of platform 1 to the Gordon Street entrance but not between the stations, and also that the route between the stations isn't flat, and that it is uneven.Just as a comparison.
To walk from the end of Platform 1 of Glasgow Central to the Gordon Street Entrance is 430 metres.
To walk from the Gordon Street Entrance of Glasgow Central to the Dundas Street Entrance of Glasgow Queen Street is 485 metres
It's not a vast distance between the two stations. 4m30s at a steady pace.
