T44 is a Swedish diesel-electric locomotive built by Nyquist & Holm (NOHAB) and Kalmar Verkstad (KVAB) in 123 units between 1968 and 1987. It was the successor of T43, and used both for hauling and shunting. It is the most common diesel locomotive in Sweden, with state-owned Green Cargo as the largest operator. Other operators include Israel Railways, Malmtrafik (two) and formerly Norwegian State Railways (one, designated NSB Di 7).
