Not a lot of geographical context here, although the central hub is pretty easy to discern. Does good work differentiating lines with a limited colour palette. Can anyone translate the legend at right that shows dashed/thin/thick lines? Is this an early attempt at frequency mapping?

Note: Thanks to all who have told me that the lines are thick for express routes, thin for normal routes, and dashed for “special” routes. So it’s service mapping, not frequency.

    5 years late, but dotted lines are “special routes,” thin lines are “normal routes,” and thick lines are “express routes.”
