1. An electronic train device for a railway vehicle comprising:
a radio module configured, through operation of at least one processor, to
support a plurality of communications protocols and a plurality of frequency bands, and
select a communications protocol and a frequency band from the plurality of communications protocols and frequency bands based on at least one performance criterion to reliably communicate with another electronic train device,
wherein the radio module is configured to auto-negotiate with the other electronic train device to determine which frequency band and communications protocol to use, and wherein auto-negotiating includes receiving feedback from the other electronic train device with respect to availability and compatibility of communications protocols and frequency bands, and
wherein the radio module is configured to switch from a direct device-to-device communication path to an indirect communication path via a base station, utilizing an Internet Protocol (IP)-based communications protocol, upon detection of the base station.
