The linked article doesn't make the slightest acknowledgement of the different PR/media environment.
40 years ago, if something went wrong with a passenger train due to the weather, it would possibly make the newspapers, maybe as a wire-service paragraph in most papers outside the affected communities. Even if there were deaths or significant injuries, or the matter lasted days instead of hours, it was unlikely to be more than a blurb on television news because there wouldn't be any eye-catching video of the train at issue, only stock footage of trains and weather.
40 years ago, nobody was calling their families or friends from stranded trains to give live descriptions of worsening washrooms and food supplies or dwindling fuel for heat. After they got to safety, they may have called their friends and families very briefly on a payphone to say they were OK now.
40 years ago, an incident might lead to an official investigation if, again, there were deaths or significant injuries or the incident stretched on unduly. And while some politicians have always grandstanded, they were unlikely then to come into an investigation with a particular axe to grind. We hadn't yet gotten to the point where freight railroads vs. Amtrak was a political parable of capitalism vs. socialism, or busy ants vs. lazy grasshoppers, or the like.
(Of which the linked article has definite undertones: the author can imagine various reasons why Amtrak is the sole cause of weather cancellations but makes no mention of hosting freight railroads "rationalizing" their workforces and maintenance resources in the last 40 years.)
Now, if something goes wrong with a passenger train for any reason, almost everyone will call or text their friends and relatives unless they're in a signal-less area. Some will send pictures of litter-strewn washrooms, or their cup of Amstew, or passengers in winter gear inside the cars.
And a couple of dozen passengers will post lurid social media posts to their followers before an Amtrak spokesperson in Washington or Chicago can put on his jacket to meet with the media. Regardless of the weather, it will be Amtrak's fault in their accounts.
And those social media posts will be gleefully reposted by politicians and social media figures who hold up Amtrak as an example of everything wrong with government.
