Opis:: The paper deals with assumptions for an open transmission in railway control applications ensuring the SIL4 safety integrity level. Using the public transmission standards, especially the wireless transmission (including radio access to Internet) requires the appropriate protection to ensure the data integrity (protection against fault and lost of transmission) and encoding (protection against unauthorized access). The estimated this way the THR values, even for single transmission channel does not differ for fault level of computer hardware in redundant structures. The theoretical results are compared with experimental tests of polish railway automation systems.

Opis:: The paper deals with additional applications of open radio transmission standards in railway systems related to safety of trains. Presented in the paper new proposition is conception of anti – collision system, which assumes safety routes both in the normal and extraordinary conditions. This solution based on wireless transmission standard and allows to significantly reduce the probability of accident (collision) especially in serviced or modernized railway lines.

Opis:: The analyses were aimed at determination of failure effects in the transmission system, which allow identifying the transition process of the system from a safety state (it may not be necessarily a failure - a free state) to a dangerous state and permit to calculate probability of the dangerous state occurrence of the system as a failure effect to the operating system. Dangerous states of the safety Fieldbus system are mainly caused by systematic failures within a specification of the system, electromagnetic interferences (EMI) and random failures of the HW effects. The effects of electromagnetic interferences and random failures of HW can be described in the paper by the use of time table.

Opis:: This paper presents selected aspects that affect information security in the GSM-R digital mobile phone network. With respect to telecommunications safety, selected methods and mechanisms have been analysed that make it possible to ensure the required level of radio coverage, reliability, availability and continuity of services in the GSM-R network. The paper also discusses selected modules for EC procedures for assessment and verification used in the technical specifications for interoperability.

Opis:: The paper deals with implementation problem of new generation of railway control and management systems dedicated for regional lines. The special infrastructure of such lines gives the possibility of application the new telematic technologies including the open radio transmission standards to control and monitoring the dissipated railway objects. In the paper the efficiency and safety analyses are presented based on stochastic process approach according to UE standards and recommendations.
