Make #trains great again — for the sake of people and the planet
As #railways enter their third century of service, research must support their renaissance for more #sustainable travel that supports human development.
Per passenger kilometre, it produces one-fifth of the #emissions of #car transport, and less than one-quarter of those of #flying. Direct emissions can be cut to zero if trains are powered by fully renewable electricity.
