[3] The Ashdown to Nashville trackage (now known as the Southern Branch), which also serves Saratoga, Tollette, and Mineral Springs, Arkansas,[3] started in 1907 as the Memphis, Paris & Gulf Railroad, later reorganized as the Graysonia, Nashville & Ashdown Railroad.
[4] After the line was relocated in the 1960's to make room for a dam project, it was purchased in 1998 by KCS.
[5] In 1960, a large feed mill was built in Waldron, and by the time Tyson Foods acquired the mill, traffic on the rail line was down to twice-a-week shipments of animal food to that plant.
[4] The tonnage today is primarily corn and soy, carbon dioxide, and chemicals such as bauxite and acid.
[2] On the Southern Branch, it interchanges with the KCS at Ashdown, and the Union Pacific Railroad at Nashville.
