The paper deals with the safety of a new train control method based on the Changeable Block Distance. Such method applies the open radio transmission standards including GPS and GSM-R for trains positioning, monitoring and controlling in a typical dispatcher area. The CBD method may be treated as a new technological overlay on classical train control systems, because it can improve the capacity of a railway line assuring the same, high level of safety (SIL4). The applied method of a Fault Tree with Time Dependencies allows to regard the time parameters of transmission connected with delays, interferences and interrupts together with reactions of the dispatcher system and of the railway staff. The results of the FTTD analysis confirm the assumed measures and suggest the trends in future applications of open transmission wireless standards in the railway control and management.
