ICT in the Polish Railway Industry

Th e article intends to discuss the impact of the development of IT and logistics systems on the development of ICT networks in the context of practical application in the area of transport, especially in the area of railway transport in Poland. At present, PKP PLK is involved in the construction of a teletransmission network, to be used mainly with ERTMS. According to the author, development of the network should be planned in such a way that this network is able to satisfy the current and future needs of all railway companies in the area of data transmission, making it possible for such railway companies to extend their range of ICT services to include other forms of transport. Systems of railway traffi c control should be established within a physically isolated fi bre-optic network (isolated fi bres in fi bre-optic cables).
