A European testing phase initiative aiming to enable electric trains to switch to emission-free hybrid operation when traveling through regions that are off the grid.

A pioneering fuel cell vehicle (FCV) from Toyota, mentioned as part of Japan's leadership in hydrogen transport.

A three-car electric multiple unit commonly used in Spanish commuter networks that will serve as the base platform for the hydrogen fuel cell train prototype.

A bi-mode hydrogen-powered train demonstrator based on a Renfe commuter train, featuring a hybrid fuel cell and battery power generation system. The vehicle can operate in electric mode on electrified track and hydrogen fuel cell mode on non-electrified sections, enabling zero-emission operation across diverse rail infrastructure.
