In 2014, ADY signed a contract with Alstom for 288m euros (341.23m USD) to supply 50 electric locomotives, including 40 Prima T8 AZ8A heavy freight locomotives – which are being produced at Alstom’s joint venture EKZ in Nur-Sultan, Kazakhstan –  and 10 Prima M4 AZ4A passenger locomotives. The latter were produced in Belfort, France and have already been delivered.

The Prima T8 is one of the most powerful electric locomotives in the world. This model is a 25t per axle two-section freight locomotive capable of towing up to 9,000t and running at 120km per hour, with installed continuous power of 8.8mw.

The Prima T8 AZ8A is designed to operate in temperatures ranging from -25°C to 50°C, requires minimum maintenance and provides high reliability levels and low lifecycle costs thanks to its modular design.
