Alstom KZ8A

The Alstom KZ8A, also sold as the Prima T8, is a broad gauge electric freight locomotive developed by Alstom for Kazakhstan Temir Zholy, the national railway of Kazakhstan. The railway ordered 200 of them in October 2010. The first were built at Belfort in France and production later moved to a new factory in Astana, with the first KZ8A off the line unveiled in October 2012. The locomotives are among the most powerful in the world, designed to haul 9,000 tonne freight trains and to cope with extremes of temperature, with an output of 8.8 megawatts and a top speed of 120 kilometres per hour. A passenger version, the KZ4AT, followed from Astana in 2019.
