"Last Train to Clarksville" by the Monkees.
This relates to the closure of Clarksville station in Tennessee. The most famous train on the Memphis Line through Clarksville was the Pan American, which had it’s beginning in December of 1921. This train was discontinued on November 15, 1965. This was due to the drop in passenger business. The Monkees came out with the song, “Last Train to Clarksville” due to this discontinuation. But that was not the last train to Clarksville. Night trains 101 & 104 ran on until February 28, 1968 when C. W. Harrison, night ticket agent, sold the last passenger ticket in Clarksville.
