Thanks to all who voted in the poll.
Here’s a test run of the design language I have in mind for the Barcelona Metro map, once I finally get to it. Figured “Vignelli ripoff” was a better look for this system, considering the signage and the complicated service patterns on the FGC lines (L6/L7/L8/L12).
Rodalies service patterns are somewhat hypothetical, based off a pie-in-the-sky dream for an additional commuter rail tunnel under the city.
As for the index, I’m almost 2/3 of the way through. After that, the legend. Should be a bit less soul-sucking to work on, I think.
