    Opis:
    Railway transport is considered the most environmentally friendly. However, taking into account all factors, (including point pollution associated with the production of energy necessary for the movement of electric traction vehicles); this position is attractive, but a little less. Therefore, it is necessary to ensure that the amount of energy produced for railway transport is sufficient, but the lowest as possible. Creating new systems whose components for correct operation require a supply of electricity, they should be designed in such a way as to consume as little energy but meeting a series of standards. The aim of the article is to review selected requirements for the power supply of a railway vehicle equipped with automatic train control devices and identification of energy demand in the scope of supplying the rmCBTC on-board system, which is being developed by Rail-Mil Computers Company from Warsaw and the Faculty of Transport of the Warsaw University of Technology. The article presents an analysis of formal and legal requirements in the field of traction vehicles. Reference was made to the list of the Office of Rail Transport and the standards not included in it − PN-EN 50155, PN-EN 61000-6 and PN-EN 50125-2. Energy requirements in the field of traction vehicles equipped with an automatic train control system have been identified − e.g. voltage range of the on-board system, permissible decays, voltage dips, disturbances and environmental requirements. The energy requirements for the rmCBTC on-board system were also identified.

    Opis:
    The development of railway transport in the current times is very noticeable, it is connected with the growing needs of movement as well as the development of information engineering. The increase in the demand for transport requires the implementation of solutions that increase the efficiency of the transport system. Both long-distance, agglomeration and metro railways can use different systems due to their specificity. Nevertheless, there is a noticeable trend in the development of systems supporting or even replacing the driver by the automation of selected activities. Such systems allow to reduce trains headway and thus increase the capacity of the line. CBTC class systems (Communications-based train control) belong to automatic train systems and are based on wireless transmission. The main purpose of using such systems is to increase the frequency of running trains while maintaining the level of safety. Computers that are on the system equipment record, process and analyse very large amounts of data. An essential element of such systems are recording units. The parameter recorders can be divided into technical and legal ones. However, for CBTC class systems, there is no obligation or requirement to use legal recorders as it is in the case of ETCS. However, it is necessary to use event recorders, and these are subject to the requirements set out in the PN-EN 62625-1: 2014 standard. The recorders are a very important component of safety systems, which is why they were analysed in this article. Both the driver, the vehicle and the infrastructure should be subject of continuous monitoring. The occurrence of an adverse event (not necessarily leading to an incident or accident) should be analysed and used to improve safety procedures. Currently, automatic systems are still developing and we are not able to accurately assess what the causes and effects of certain events may be, which is why data collection and analysis is particularly important. The article presents the general specification of the CBTC system. The parameters and properties of driving recorders should be presented. This article is cofinanced by the European Union POIR.01.01.01-00-0276/17
