St. Louis has a dinky light rail system, Metrolink. It has one very long line, from the airport to downtown, across the Mississippi via beautiful old Eads Bridge and then way, way out into the Illinois suburbs. A couple of years ago, a spur opened from from the Central West End of the City, through Clayton, the seat of St. Louis County, and then a bit south through some areas where hardly anyone goes.
The lines were laid out on the cheap by following old railroad rights-of-way, rather than acquiring land through places where people actually need transit services. I can't complain, though. There is a stop under my office building, from which I can get to the airport for $2. You must buy a ticket and then validate it with a time stamp. The ticket validation machine in this picture is at the top of the 8th and Pine station downtown, right on the corner where I work.
TOMORROW: A very big, very patriotic motorcycle
