Joplin is served by the mainline of the Kansas City Southern (KCS) railroad, as well as by branchlines of the BNSF Railway and Missouri and Northern Arkansas Railroad (MNA). The city was once a beehive of railroad activity; however, many of the original railroad lines serving Joplin, such as the Missouri and North Arkansas Railroad, were abandoned after the demise of the mining and industrial enterprises. The Missouri and North Arkansas had connected Joplin with Helena, Arkansas. Passenger trains have not served the city since the 1960s. The Joplin Union Depot is still intact along the KCS mainline, and efforts are underway to restore it. Despite the decline in some rail lines in and around Joplin during the past five decades, many of the original lines still remain. Aside from the former Frisco Railroad route from Joplin to Webb City and the Carthage to Wichita, Kansas, lines that have since been converted into bike/hike trails, most of the original routes still remain in place under the control of the BNSF, KCS, and M&NA railroad companies.
