Development of sophisticated novel sub-systems for controlling railway operations, and processes for collecting and distributing information related to those operations is currently ongoing. The collective aim of many of these developments is to increase operational efficiency, resilience and capacity by developing and implementing integrated and digitised railway operational systems. Connecting information sources and outputs, and enabling implementation of optimised operational decision-making and decision implementation. This paper summarises first the background, i.e., the relevant topics in this area, and then presents the Integration Layer (IL) and demonstrator platform for traffic management approach that connects the relevant systems and provides a virtual testing environment for ongoing developments in traffic management systems (TMS) respectively. The IL concept and demonstrator platform is currently developed in the EU-funded Shift2Rail (S2R) project OPTIMA. The article discusses the need to test the novel TMS sub-systems and their modules in a virtual environment and details the proposed testing procedures to be implemented in the OPTIMA project for the integration layer and communication platform demonstrator itself and for the initial candidate modules developed by the relevant S2R members from railway industry. The target of the virtual testing to be carried out in the OPTIMA project is to validate the developed integration layer and communication platform demonstrator as a testing environment, and the performance of the candidate sub-systems in a relevant controlled environment, with representative interfaces and interactions with other sub |
