The Electro-Motive Division GT22HW-2 is a custom designed EMD A1A-A1A diesel-electric locomotive built by Đuro Đaković for Yugoslavia. Mainly used for passenger service, the reliability of these locomotives made this model a success even after the breakup of Yugoslavia. Designated as the Series 645 in the Yugoslav Railways, these locomotives were later known as the Series 2044 in the Croatian Railways after 1991. Thirty four examples (645.001 - 645.034), of this model were built between February 1981 to August 1984 and were given four different lettering variations due to the various ethnicities existing in Yugoslavia at the time.
