Pushing the boundaries

Imagine not having to get off your train and take a new one whenever you must cross a border, as the infrastructure or signalling systems are different or as you get to the end of the electrified section of a line. Thanks to the interoperability and innovations of Traxx Passenger locomotives, Alstom makes it possible to cross geographical borders or continue running into non-electrified sections without changing trains. On top, low noise and particle emission contribute to maximising passenger comfort, ensuring a smooth ride.
