Not insurmountable, but still a mountain to climb. As a result, many industries stick to tried-and-tested methods in preference to getting new techniques passed by the RSSB and the like, especially when the gains are arguably small.All solvable though. The 777s themselves have onboard Wi-Fi and a network for secure comms (cctv, pa, diagnostics) as well as the passenger side. Interference wouldn’t be an issue given the box would be paired and communicating with the train itself, which the guard would be standing inside.
Proving it all works and is secure is the only major challenge, but it’s not an insurmountable hurdle.
That'd give much the same benefit for little added complication. No (questionable) radio links between the human being and the door controls, and the guard could fall back to using the door buzzer if needed.Almost might as well make it secure audio comms and the driver presses the actual button. I think PKP IC's FLIRTs are operated like that.
