Something we’ve only just noticed on carriage maps of District Line trains is the way that the shuttle service is shown between Olympia and High Street Ken.
Obviously trains to/from Olympia are very infrequent and are thus shown as a dotted line, but why then does the in carriage map show the ‘shuttle’ service as being a solid line to High Street Ken?
Yes, there are regular Wimbledon to Edgware Road services (as well as the Circle) which makes this a non-restricted service, but following the logic of the carriage map here, it’s clearly showing a shuttle service between Olympia and HSK, in which case shouldn’t the green line between Earl’s Court and HSK also be a dotted line instead of a solid one?
Solid line to HSK
