C'est simple - What is interoperability? - EN

If a train has to travel from Latvia to Portugal, i.e. cross several countries, it has to be equipped with many different signalling systems and it has to adapt to the different networks. Something that a truck just doesn't have...
The challenge of interoperability is to remove the barriers faced by trains so that they can travel as freely as a road truck.
Do you want to know how it works? And why? Then get on board, it's all happening in this carriage!
