As if we didn't have enought problems, President Biden recently issued a warning of the possibility of a Russian cyberattack on critical infrastructure in the U.S. I’m assuming that this means that satellite communications, the internet and our computers could get seriously messed with or even shut down. If this does happen, how will it affect AMTRAK passenger service? If a train is already underway towards its destination and the computers go down, will it have to stop and wait until the computers come back on-line before it can proceed? Your comment, please.
