Infrastructures.

Infrastructure is the backbone of the railway: our figures on our network, our fixed installations as well as installations used for producing and distributing electricity for railway operations show the central importance of our infrastructural installations. All of this is complemented by maps of the network and construction projects, as well as diagrams providing comparison of energy consumption and greenhouse gas emissions, complete with international comparisons.
