ETCS variables

This page outlines how ETCS variable values are assigned and coordinated. It details that ERA manages international values, Member States handle national values, and provides instructions for requesting ERA-coordinated values, including filling out and emailing specific forms.

The use of some ETCS variables requires co-ordination, including the definition of who is assigning new values. Care has to be taken not to assign identical values for different purposes or vice versa. Reasons for this may be functional or safety related.

Based on the functionality behind each variable, a list for the organisations responsible for assigning values to them has been established (see section 3.4.1.1 of Subset-054) and can be classified as follows:

  • For variables which need international co-ordination, ERA maintains public tables allocating unique values or range of values to the requesting organisations
  • For variables which need national co-ordination, the Member States are responsible for assigning unique values.

For ETCS variables whose values assignment is under the coordination of ERA, fill in the request form and, if applicable, the specific additional forms. Then send them back to us by request [dot] etcs_variablesatera [dot] europa [dot] eu (e-mail).
