The analysis of the RADIOSTOP railway alarm signals in the VHF 150 MHz radio communication network was conducted. The service of the REC emergency call in the GSM-R system was characterised. Then, the technical problems related to the generation of alarm signals in the migration period were described. In addition to the problems associated with the technical aspect of connection of both alarm signals, the issues resulted from their radio range were analysed. Emergency call service REC / e-REC in the GSM-R system, analysis and assessment of the implementation of the emergency call function during the migration period, phases of the REC emergency call, railway emergency call service, generation of the alarm signals during the migration of systems, differences in the range of the GSM-R and VHF 150 MHz systems, implementation of GSM-R on the entire railway line are presented in the paper.
