NDLI: Direct train-to-train communications at low UHF frequencies

Abstract	Fundamental modernisation of railway transportation is on the agenda of the next generation train project funded by the German Aerospace Center DLR as well as the Roll2Rail project within the Shift2Rail initiative. Reliable direct train-to-train (T2T) communication can significantly enhance train control and signalling towards semi- or fully autonomous operation, in order to significantly increase the efficiency and safety. With terrestrial trunked radio a communication standard is available with high potential for this use-case. It offers the ability of direct communications between vehicles, i.e. ad hoc communications over several kilometres. The authors summarise the results of T2T measurements conducted at 450 MHz. The authors will characterise the propagation conditions and assess the link performance by analysing transmissions in different scenarios and railway environments.
