The Camp Robinson spur once served Camp Robinson (home of the 39th Infantry Division of the National Guard) in North Little Rock, AR. While the installation is still in operation, the spur last saw use during the first Gulf War in 1991. Today, the line has fallen to disrepair as UP has not maintained the line since the mid 1990s -- a washout has rendered part of the tracks unusable, downed trees from severe weather block other parts of the track, and even the switch off of UP's Van Buren Subdivision in Levy (LEEvee) has been removed.
However, the line has not officially been abandoned. UP filed for abandonment in the 1970s, and even the city of North Little Rock wants to convert the right-of-way to a rail trail when it becomes available. But the U.S. Army still sees value in the spur, possibly for some future conflicts that would require rail access to Camp Robinson; thus any attempts to abandoned the tracks are held at bay.
And so the track remains, waiting for a train that will probably never come.
