The advantages of modularity

A member of our Prima locomotive range which benefits from our 100-year experience in locomotive design, the Prima M4 is based on a flexible platform with modular architecture, offering the most up-to-date developments and solutions. Owners even have the opportunity of changing the locomotive’s purpose from freight to passenger service simply by changing the bogie.

Reliable and available

The modular approach means that spare parts and maintenance are easier to manage, but the Prima M4 is a low-maintenance locomotive which can be equipped with TrainTracer and monitored on our HealthHub. Our expertise in maintainability thus improves the availability and reliability of rolling stock.

Driving in comfort

But we haven’t forgotten an important aspect of the locomotive: the driver. The Prima M4 is especially suited to long-distance passenger or freight operations and the most extreme weather conditions. The large cabin is fitted with a range of optional features such as climate control, heated seat, cooking and storage space and a toilet on request. It can also accommodate the European Driver’s Desk, offering the most user-friendly driver experience.
