TCMS Data Service
A voluntary specification for a functional description for data service (called TCMS_DS), including a functional interface description from TCMS to non-TCMS functions for use by companies in the rail sector. This EuroSpec provides a common specification for TCMS_DS in rolling stock between train operators. This specification is applicable to rolling stock that is equipped with TCMS_DS. It shall be possible for the operators to choose a subset of the TCMS_DS requirements depending on their train operation in order to reduce hardware costs. This specification is an add-on to the Technical Specifications of Interoperability (TSI). The specification contains requirements at system level of the TCMS_DS and its interfaces, and unifies the requested performances of the different operators.
