Alstom has shipped from France the last three Prima M4 (AZ4A) locomotives which will soon enter Azerbaijan rail passenger services.

In October 2017, Alstom presented in Belfort, France, its first Prima M4 passenger locomotive for Azerbaijan Railways (ADY). 10 Prima M4 passenger locomotives were manufactured in Belfort. Schliess- und Sicherungssysteme GmbH has delivered the cab entrance doors for these locomotives.

Prima AZ4A is able to run at 160km/h in passenger service and requires minimum maintenance and provides a high reliability level thanks to its modular design.
With around 3,000 km of track, the Azerbaijani railway network is an important link between the Black and Caspian Seas and between Russia and Iran.
