MIAMI HEAVY RAIL
A Single, Long Line

Miami's Metrorail runs along 22.4 miles of elevated right of way.  It passes above varied neighborhoods, and gives rather appealing views of the (too distant) downtown area.   

The service is operated by Miami-Dade Transit, which also provides extensive bus service within the county.  This photo is at Okeechobee in the late-1990s, then the terminal to the northwest.  The route has since been extended one further station west to Palmetto.
