This is the current map (as of May ‘17). This version has the definitive design for the newer lines under construction (Line 3 and Line 6). And finally, they’ve decided not to include the airport on the map, even tho’ there’s some rumors floating around that a planned extension of Line 1 or a new “Line 7” could reach it once and for all.

This is a whole new look for the Santiago Metro diagram, previously reviewed in 2014 and 2012. The background is now grey, with a darker area representing the city proper. This works quite well, although the whole thing feels off-centred to me, with a large gap along the left edge of the page. 

The route lines are much thicker compared to the previous version, which is an improvement, although the new purple Line 6 takes a very wobbly path across the city to accommodate the slightly over-complex street grid that lies beneath the route lines. The long-overdue Line 3 finally makes an appearance on the map, though it’s still shown as under construction… beaten to the punch by the afore-mentioned Line 6.

I’m sad to see the removal of the BiciMetro and BiblioMetro icons, both of which seemed to me to be unique aspects of the Metro system (And yes, I checked – both programs are still running). And speaking of icons, is this map completely missing a legend?

Our rating: A new look that seems a little bolder and more confident than previous iterations. The street grid is a little fussy and overworked, but does the job. Loses some information about services compared to older maps. 3.5 stars.
