With 645s howling and the Airchime P3 Screeching, a pair of ex. SP SD40M-2s and an ex MP SD40-2 grind the daily MNA wayfrieght uphill at MP 260. Eventually, the train will return to Carthage Missouri, only exercising trackage rights from Rock Creek Junction, to Pleasant Hill, MP 249. The Missouri & Northern Arkansas operates on the ex. Missouri Pacific Carthage Subdivision, which begins at Pleasant Hill and stretches into Arkansas. The "Armour Yellow" SD units are relatively new to this railroad, acquired as part of a multiple unit purchase last year, by parent company Railtek.
