And it wouldn’t be long before high speed rail would require IDs anyway. There’s not some intrinsic reason why rail doesn’t require that stuff & it’s as much of a terrorist target as any other form of transportation.
I used to take Amtrak to/from Chicago 2-3 times a year, and once as I was headed back home TSA had set up shop at the Chicago station and was checking everyone.
I don’t travel by train these days so I have no idea whether that has happened again.
Does it matter? The terrorists (eg TSA) are attracted to anything popular they can make up a plausible panic narrative about. If trains became popular, they'd set up shop at train stations. In fact I think they're already doing "spot check" performances to trains.
Less than a year ago, a disastrous train derailment sent a massive plume of dangerous chemicals billowing over East Palestine, Ohio, startling the town of nearly 5,000 residents and onlookers nationwide.
Now, a new report warns that more of these catastrophes may loom: At any given moment, more than an estimated 3 million people are unknowingly at risk, as toxic trains full of a highly combustible and carcinogenic chemical used to make plastic move between Texas and New Jersey.
