​We offer a means of transportation that is more consistent with a sustainable development model, given its low power consumption, ability to adapt to renewable energy and minimal CO2 pollutants.​

Travel responsibly on our trains and combine the pleasure of traveling with respect for the environment.


The railroad is the medium that carries a lowest CO2 emissions per unit transported - between 3 and 5 times less than travelling by road and 7 to 10 times less than traveling by plane.

These lower emissions are due to:

-Power consumption: fuel efficiency

The use of regenerative braking allows some trains to put between 6 and 10% of the energy used at high speeds back into the network.

Operating our trains economically allows energy savings of up to 10% on certain routes.

-Public transport: less energy

The railroa​d, like other means of public transport, uses less energy than less efficient forms of private transportation.​

These factors mean railroads consume between 2 and 5 times less energy per unit transported than other means of transportation.

​ ​​​

-Reduction of local emissions

The consumption of electric power reduces emissions of local air pollutants that cause serious diseases, such as sulphur and nitrogen oxides, carbon monoxide, particulate matter and volatile organic compounds. This avoids contributing to urban pollution, unlike road transportation.

-Lower noise emissions​

Railway noise is punctual and less bothersome than road noises.​​ 

It is possible to implement noise combatting measures for railways, infrastructure or train cars.​


-Use of space​

The railway uses between 2 and 3 times less space per unit transported than roads. In Europe, the railroad holds 8% of the market but uses only 2% of the territory for transport.

Although the construction of high-speed lines does take up space, these lines occupy 35% less area than a two-lane highway in each direction.​
