Compatability

These maps fit together smoothly; the official Toronto subway map (http://www.toronto.ca/ttc/pdf/subway_rt.pdf) and the two streetcar guides created by Matthew Blackett of Spacing (http://spacing.ca/wire/?p=2691)

This has perfect relevance to the project as a way to juxtapose the links between mainstream and underground.
The skill seems to be in applying the same visual language to different sets of information, as would have been neccessary with the independent services of the first London Tube map.
