The article presents problems related to the implementation of railway investments related to obtaining authorization for placing in service of structural subsystems. The main purpose of the investment is to increase speed on railway lines while keeping or improving the level of safety. All modernized railway lines are subject to the certification process. Any interference in the certified subsystem involves the need to assess the introduced change in accordance with the requirements of the common safety method for risk evaluation and assessment. Such assessment may also generate various interpretation problems, therefore it is necessary to assess the impact of implemented investments on already built-in devices of the control - command and signalling subsystem - trackside equipment.
