It is important to asses ETCS confi guration in view of the functionalities, which are expected to be ensured. As examples we can point: covering LX protection functionality, and revocation of an already given authority.
On a majority of conventional lines, the LXs exist and it is not possible to replace all of them with viaducts or tunnels due to huge costs of such investments. The ETCS confi gurations offer different functionalities, which can be used for refl ecting LX protection in data transmitted from track to train. If there is a wish to ensure covering LX protection functionality it is important to decide how and answer whether this is possible for all or only for some ETCS configurations.
