I’m trying to find all the direct connections between stations on any line.
In the route of the line, any two adjacent stations should be directly connected. However, in this list i end up with this ‘Wimbledon Underground Station’, ‘Edgware Road (Circle Line) Underground Station’
Now from what I know, these two stations aren’t connected. So why does this occur?.
There isn’t a separate Edgware Road (District Line) station. The Circle, District and H&C lines all serve the four platforms at one station and the Edgware Road District lines all (or almost all) serve Wimbledon.
The service you refer to is called the “Wimble-ware” service, one of the district line services.
The “Circle Line” is a virtual line that use the H&C/Met on the north side of the loop and the District on it’s south side with a tiny unique link in-between.
