History

During the 1970s the Turkish State Railways decided to replace their 800 steam locomotives with diesel. This quite delayed task required the delivery of more than 400 diesel units. On February 15, 1968 TCDD and MTE signed an agreement for delivery of the DE24000 and the DE18000. TCDD opted for the larger Co'Co' engine, and only five were delivered of the smaller Bo'Bo'.
