Arkansas and Missouri Railroad

The Arkansas and Missouri Railroad (reporting mark AM) is a Class III short-line railroad headquartered in Springdale, Arkansas.

The A&M, as it is known, operates 139.5 miles (224.5 km) of line from Fort Smith, Arkansas to Monett, Missouri. The railroad interchanges freight cars with Kansas City Southern Railway at Fort Smith, with Union Pacific Railroad at Van Buren, Arkansas, and with BNSF Railway at Monett. A branch line connects Bentonville, Arkansas, with the main line in Rogers, Arkansas. A&M also leases 3.2 miles (5.1 km) of track (locally known as "the Bottoms") from Union Pacific at Van Buren, and provides haulage services for Union Pacific between Van Buren and the Fort Smith Railroad in Fort Smith.

Freight operations are based out of the headquarters location in Springdale as well as Fort Smith. Freight customers are predominantly located in those two geographic areas. The rail line was substantially upgraded between 2002 and 2005 and features continuous welded rail across its entire main line. The line handles 286,000 lb (130,000 kg) railcars and has vertical clearances sufficient for double-stack intermodal cars throughout. Most traffic is handled in scheduled freight trains although shuttle trains of corn make regular appearances in the Springdale area using locomotives from Union Pacific. Freight services operate seven days per week.

Traffic generally consists of grain and feed supplements, paper products, sand, plastic, food products, steel, scrap, lumber, aluminum, and mineral products.
