It's either that or starlink, some railroads in Germany go through areas without any mobile network signal. Think about how crazy that is in 2026 when everything expects everyone to be online 24/7/365.
It's my understanding that most rail/rail collisions are the result of poor communication.
The railroads have their own mobile network, GSM-R, it's in the article...
They aren’t using starlink for safety critical comms
