The EUROSIG specifications were subsequently updated by the UNISIG Consortium 4 in consideration of further technical work in development and test areas. The UNISIG technical documents were finally submitted to the CENELEC WGA9B group for review, integra- tion, and consolidation. The main body of Part 1 of this Norm, and the relevant Annexes designated as “normative”, constitute the man- datory requirements for achieving air-gap interoperability between any possible combination of wayside and train-borne equipment. Annexes designated as “informative”, either provide background information for the mandatory requirements, or outline non-mandatory requirements and optional functionality. Part 2 of this Norm (UNISIG SUBSET-085) specifies test methods and tools for verification of compliance with the mandatory requirements of Part 1 (this document). 1 The EUROSIG Consortium was composed of the following European Companies working in the Railway Signalling area: ACEC Transport, Adtranz Signal, Alcatel SEL, GEC Alsthom Transport, Ansaldo Trasporti, CSEE Transport, SASIB Railway, Siemens, and Westinghouse Signal. 2 UIC: Union Internationale de Chemins de Fer. 3 EEIG ERTMS User Group: European Economic Interest Group was composed of some European Railways managing the implementation of ERTMS/ETCS trial sites aimed at full functional verifications. 4 The UNISIG Consortium was composed of the following European Companies working in the Railway Signalling area: Adtranz Signal, Alcatel, Alstom, Ansaldo Signal, Invesys Rail, and Siemens.
