What would it look like if you took a platoon of helicopters and airlifted the entire Chicago L system and dropped it on Detroit? It would look like the map you see above. The map was made by a reddit user, who goes by the handle “northsider1983.”

The map gives a sense of the scale of both cities, and their very different transit options. Detroit, of course, doesn’t have a rail system. It has the People Mover, which covers all of 2.9 miles. It’s pretty arguable whether Detroit even has a functioning bus system these days (though there was a time when Detroit’s streetcar system was far more extensive than today’s L).

But Detroit’s transit dreams still have some life left in them. Businessman Dan Gilbert said again this week that he expects the new light rail line along Woodward Ave. “will be in the ground by the end of this calendar year.”
