Over course of this year, several international railway safety experts have discussed what the proper definition of a railway safety barrier might be in the digital world. The UIC work group has discussed many aspects of safety management and safety barriers, including existing and proposed legislation, safety management systems, barrier models, and various hierarchical arrangements of barriers.
It has settled on a number of common definitions for safety barriers to support improvement in safety and interoperability globally. The definitions are formulated semantically; that is to say, the definitions are ready for current and future semantic models of railway safety. In this way, UIC is paving the way for the future of safety on the railways.
