The communications system is not novel. It's GSM-R, which is good old 2G cellular with some special railroad features. Both voice comms and signalling run over that system. Since both went out, the comm system must have failed.
- YouWhy 2y agoDo we know for certain that a major cause of the failure has been a GSM-R failure? Industrial grade communication systems tend to be very well behaved in terms of fault detection and management. I'd be very surprised if the whole whack-a-mole dynamic described in the post was a failure mode of GSM-R system per se.
