New Siemens-equipped locomotive runs at record speed


On October 30, 2010, locomotive KZ4Ac0007 reached a speed of 200 km/h during a test run near Saryoba in Kazakhstan. It was the first time that a locomotive in Kazakhstan had ever run at this record speed.
These Class KZ4Ac passenger train locomotives are being built by Zhuzhou Electric Locomotive Co., Ltd. The order had been placed in October 2008 by the national railway company Kazakhstan Temir Zholy (KTZh). Siemens is in charge of supplying the traction and control equipment, which is the heart of the locomotive. In addition to the converters, traction motors, SIBAS control units and displays the Siemens content also includes services such as engineering, commissioning, tests and training.
Of the total 22 Class KZ4Ac locomotives ordered, four have been delivered to Kazakhstan since July 2010. The locomotives are to be used in passenger service between Astana, the capital of Kazakhstan, and Almaty, its largest city. They designed for a line voltage of 25 kV and a top speed of 200 km/h.
