Description
DE33000 is an EMD (Electro Motive Division) type GT26CW-2. At the time of the first delivery in 2003, EMD was part of General Motors but EMD was sold to Caterpillar in 2012. The DE33000 were built under EMD license by Tülomsaş in Eskişehir.
The GT26 is a well proven diesel locomotive and the export version of the SD40-2. The GT26 was exported in several countries and is part of the large family of locomotive using the successful 6451 engine. In Turkey, this family was already represented by the DE22000. The DE33000 is very similar to the DE22000 and shares many common parts. The key difference is in the presence of a turbocharger on the DE33000 allowing for a greater power.
The GT26CW-2 is a design dating back to 1972 and was somewhat outdated at the time of the order in 2003. TCDD could have chosen a more modern loco based on the 710 engines, like the JT42CWR, also known as class 66, the most popular EMD loco in Western Europe at the time. Interestingly, TCDD stuck also to the single cab body requiring the engine to be turned when reversed.
The resulting DE33000 is externally very similar to the DE22000, allowing only for minor change and in the body and the frame which is 1,8m longer. The first 6 units were delivered with the same cab as the DE22000 and the same red livery. A second white band was added to help distinguish both locomotives.
From DE33007, the cab design was altered to allow for more space inside the cab. The roof was modified and the small front windows replaced by a single large one. Surely the contort of the cab was improved, but no changes were made to safety despite the numerous level crossing accidents in Turkey. These units received also a new white / blue / red livery. This livery was later applied to DE33001 to 6 as well.
All DE33000 received a dual coupling: the classic buffer / screw and the SA3 automatic coupler which is now used by TCDD on block trains.
The first units were delivered in 2003 to undergo acceptance trials. As of 2004, 6 units were being delivered. The total 1st order was for 65 units, this quantity being then increased to 89. DE33035 was spotted in service in September 2006. DE33065 spotted in the erecting hall at Tülomsaş in May 2008. DE33073 was spotted in Konya in February 2009. DE33075 spotted in Ankara in March 2009. DE33086 spotted in Eskisehir in June 2009. The DE33000 are employed all over Turkey, predominantly on freight traffic.
