History
In 1920, the only modern power the SCP had was a batch of 10 compounds 2'C (TCDD 35001) built for the opening of the Bandırma branch in 1911. But the compound mechanism was difficult to maintain due to lack of skilled manpower. All the other units were outdated engines from the 19's century. Therefore, the SCP placed several orders for new engines, including this single expansion 1'E supplied by Corpet Louvet.
Corpet Louvet is a manufacturer that was specialized in narrow gauge engine. It seems that this standard gauge Decapod is the only one of this kind to have been built by this manufacturer. The reasons why Corpet Louvet was chosen are not known. No doubt that the economic factor was the main driver and the price offered by Corpet Louvet was good.
The experience of Corpet Louvet at making lightweight engines must have been useful. This Decapod is only 13,5T per axle, a perfect value for the lightly built lines around Izmir. The 56911 is otherwise a modern engine, yet simple and reliable. It had all the desirable equipment for the time: feed water heater, slide valves, large cylinder, Crampton firebox and superheating. These engines proved very good and stayed into service until the diesels took over well into the 1980's.
