Blight Rail allows tourists to view the ruins of Detroit.
At $46 million per mile, it certainly isn’t the most money spent on light rail in the country in terms of capital cost; AFAIK, that dubious honor belongs to the Newark NJ light rail extension, at $275 million (for one mile) in 2016 dollars. (Even though there’s an underground segment, the tunnels were already there from the time of the Cedar Street Subway.)
Sorry; make that 2014 dollars. I don’t have an inflation calculator that goes two years into the future :)
