Unofficial Map: Circular Tube Map by Maxwell Roberts
Apparently, circular Tube Maps are like London buses — none come forever, then two arrive at the same time.
This one is by Maxwell Roberts, an expert on the London Underground map if there ever was one. He’s personally redrawn multiple, multiple versions of the map in just about every possible configuration, just to see what works and what doesn’t. Many are featured in his excellent book, Underground Maps Unravelled, which I promise I’ll review properly one day.
Wisely, Roberts has confined his map to the traditional view of Greater London itself, with trains headed to distant places given an arrow pointer towards that destination.
Interestingly, most of his route lines radiate out from a central point, but some run parallel to other routes instead. This makes the design less rigid to a design ideal, but also upsets the visual flow of the diagram in a couple of places — I find the parallel Bakerloo and Metropolitan Lines in the northwest part of the map quite jarring.
Roberts’ interchange stations are much tighter than Fisher’s, looking far more like “traditional” Tube Map markers, but some are still very convoluted in making their connections between lines, such as at Farringdon/Barbican.
The London Underground logo "hidden" in the Circle Line is a bit of a gimmicky design affectation, although it actually works surprisingly well in the context of the diagram.
Overall, I think this version is more successful than Jonny Fisher’s, although I still don’t really see it as a viable alternative to the current official map. Neither does Mr. Roberts, who says, “Overall though, I don’t think I will be sending this one to TfL for comments. No great advances in usability here, but it was fun to make it.” Three-and-a-half stars.
