A radio apparatus and system for a railway infrastructure are described. The apparatus comprises two separate radio units, operating in non overlapping frequency ranges (e.g. 2.4 - 5 GHz and 868 - 900 MHz). The system comprises a on-board radio apparatus and several trackside radio apparatuses, each radio apparatus having two separate radio units. In the on-board radio apparatus, the radio unit operating in the higher frequency range transmits/receives data using a radio link set up with a single trackside radio apparatus at a time. Besides, the radio unit operating in the lower frequency range transmits/receives the same data using radio links set up with multiple trackside radio apparatuses at the same time. The apparatus and system therefore have redundant structure, which allows the implementation of mechanisms for protecting transmission of data between trackside and on-board side (in particular data which is vital for the safety of the railway infrastructure).
