An anonymous follower asks: “Do you have any examples of a line map for a loop/circle line? I’m curious as to how those are implemented.”
Transit Maps says:
Generally, a strip map for a loop or circle line follows much the same principles as a usual one, although the available space may have to be used a little more creatively in order to fit things in. Above are a few interesting examples.
London’s Circle Line: With recent additions, this line is no longer a true loop – for which the travelling public is sincerely thankful, as any problems on the Circle used to impact the District and Hammersmith & City lines terribly, throwing much of the Underground into chaos. From the picture above, it can be seen that the Circle Line’s strip map utilises a much deeper space above the doors than many Underground strip maps do. Often, they run in a single, shallow line above the windows of the carriage. The other lines that share track with the Circle Line are also shown, but not lines that cross it: these are shown as standard interchanges instead.
Chicago’s Orange Line: This line runs around Chicago’s central Loop and returns back the way it came. The map handles things in a pretty straightforward way, although, interestingly, the thickness of the route line halves while it’s going around the loop. The direction of travel around the loop is clearly indicated with arrows.
Tokyo’s Yamanote Line: Of course, the Japanese use technology to display information about their famous circle line! Each car on the Yamanote Line has LCD displays that indicate the current station (the red box), as well as the estimated time to the next few stations. The display alternates between Japanese and English information.
Glasgow Subway: Well, the whole subway is a loop – earning the system the nickname “The Clockwork Orange” – so all their maps look like this. Despite the inner and outer loops travelling in opposite directions, this map neglects to point out which one goes where!
