[AZ] AZ8A: Alstom presents its freight locomotive for Azerbaijan

Alstom today presented the first Prima T8 AZ8A electric freight locomotive for the Azerbaijan Railways (ADY). The event took place at Alstom’s site in Astana, Kazakhstan, where 40 such locomotives are being manufactured by Alstom joint venture EKZ.

The first AZ8A forms part of a 2014 contract awarded to EKZ by ADY for a total 50 locomotives, including ten Prima M4 AZ4A passenger locomotives.

“Today we are very proud to present the result of strong collaboration between Alstom and ADY: the very first freight locomotive produced for Azerbaijan at our plant in Kazakhstan. We are pleased that this locomotive will be part of the development of the transit link between the Caspian and Black Seas, Russia and Iran – an intersection where Azerbaijan, with its 3,000 kilometres of line, plays a key role,” said Bernard Peille, Alstom Managing Director for the Western and Central Asia Cluster.
