I know that the designers who produced this new map had the best will in the world, and showing different lines in different colours is certainly an improvement over the confusing old yellow and blue map. But by trying to cram as much as possible in, including rural trains, it looks a bit cluttered and it is not as easy to read and interpret as it could have been.
If they really wanted to include rural passenger lines (which are of no relevance to suburban commuters the map is designed for), they might have included the rural lines as a smaller inset at the bottom, but only showing the major towns rather than every minor hamlet that has a railway platform. (Yes, I'm thinking about you Talbot and Pyramid Hill.)
While it's useful that they show Skybus as a "skinny grey line", I'm relieved that they decided not to also show trams and buses in their sincere but misguided desire to cram as much as possible onto the map.
