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, Malmtrafikk (two) and formerly Norwegian State Railways (one, NSB Di 7).

History

Though mainly used for shunting and freight hauling, T44 has occasionally been used to haul passenger trains. In the 1970s it was used on the unelectrified line Borlänge-Mora, and in 1990s on Inlandsbanan. Compared to the predecessor T43, T44 is more powerful and has a modernized drivers cab, with better noise insulation, though there are many similarities between the models. In appearance the T44 is somewhat more square than the predecessors. Up to three T44s can run multiply.

In 1993, SJ T44 276 was sold to the NSB for use as a shunter on the Ofoten Line, and given the designation NSB Di 7, and numbered 634. This engine was transferred, along with SJ T44 283, to Malmtrafikk in 1996. When Statens Järnvägar was split in 2001, Green Cargo took over all the T44 locomotives, though four were sold to the Swedish railway company TGOJ (now a subsidiary of Green Cargo). In 2007, Green Cargo has ordered a full renovation of 100 units from Bombardier Transportation which included new four-stroke engines from MTU (type 12V 4000 R43).[1]. The renovation is expected to extend the life-time with 15–20 years.[2][dead link] The first rebuilt units was delivered in 2009 and is called Td
