Plane vs Train Security

We took Amtrak up to New York earlier this month and I was struck by the difference in the level of security versus flying

On a plane, you have to show your ID at the counter and your name must match what's on the ticket. Typing too fast online and misspelled your own name? You've got a problem

Your carry on bag goes through an x-ray machine (I'm sure checked luggage has some kind of protocol as well)

You go through a metal detector, maybe get patted down

On a train, I can buy a ticket and pass it along to any bozo I want to, as long as the ticket scans it's all good

Nobody touches my bags

Anyone know why the vast differences between the two travel methods?

What's to stop someone from loading up a bag full of explosives then detonating it?
After the Oklahoma City bombing there wasn’t a national response to make it harder to rent white vans

Drug deaths and gun death are both at near pandemic levels but cough syrup is policed more than guns

We have deep cultural mythology for both cars and guns
There is great fear of both planes and drugs bc they are seen as the loss of control
We pretend like we have control over cars (and guns) - there’s even more ‘control’ over trains since they are on tracks, the damage they can do is limited to things that cross or are in close proximity to the tracks
We culturally have much less anxiety about that
