Most of the information that has been removed isn’t essential for most commuters; however, as Londonist points out, the removal of zones might cause issues. Personally, I don’t need zones on my day-to-day commute. However, this is crucial information if I’m travelling to some far-flung Tube station. How do I get this information now? I’m not sure. Do I have to wait in the ticket queue just to ask a TfL employee what zone Station X is in? At the moment, I can download the old map from the TfL site, but I wonder how long it is before it disappears. Of course, if I plan my journey in advance, I can always get the zone information from Wikipedia.
This raises some interesting general questions: Is less clutter a good thing when vital information has been removed? Is designing for the 80% always the best idea? When removing rarely-used features, what alternatives should be provided to ease the transition to the new, simpler version?
I should add that I really do miss the Thames, even though I can see that it doesn’t add any useful information.
