The report addresses the queries on the conformity assessment of the Construction gauge characteristic of the Commission Regulation (EU) № 1299/2014 from 18 November 2014 regarding the technical specifications for interoperability related to the infrastructure subsystem, which is mandatory for the application in modernization and renewal of railway sections of the main and wide-ranging railway network of the European Union. When the conformity is being determined, the applicable kinematic dimensions for the upper part are GA, GB and GC, and for the lower part - GI1 and GI2, as defined in standard BDS EN 15273-3. Performing kinematic calculations to prove compliance for each project is a complex and time-consuming task for the design teams, which is why the use of construction gauge greatly simplifies the process, including the process of maintaining the railway system. In solution of this problem, the infrastructure manager has issued an order №1844 / 14.10.2019 for determining the construction gauge GUC-BG on the basis of the gauge GUC defined in BDS EN 15273-3. At the moment there are no rules and defined construction dimensions regarding the application of GB and GA dimensions. This report examines the results of kinematic calculations performed for the most unfavourable profiles for GB and GA kinematic gauges and analyses the main aspects of determining the construction gauge applicable in proving conformity.
