TCDD DE 24000 are a type of diesel locomotive built for operations on Turkish State Railways by Tülomsaş. A total of 218 units were built between 1970-84 on license from Matériel de Traction Electrique of France. The DE 24000 formed the backbone of the dieselisation of the Turkish railways during the 1970s.
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 DE 24000 along with the delivery of the smaller DE18000. But to be able to build up domestic competence on diesel engines, it was decided that the production would be done by Tülomsaş of Turkey.
