"Although there is clearly some communications protocol which links the train-provided devices, my systems cannot detect it, or interface with it. Beyond that, no networks exist outside of potential local ones generated by the very few of us who are nonbiological." Frankly, Orisa preferred that. Her systems were protected with state-of-the-art defenses, but unknown threats were far harder to stop. Who knows what weird communications might come through if they could reach her?
