It's not clear to me that it "changed things in important ways" in this case if a call alleging serious damage to the rail would've similarly triggered a pause for inspection.
A phone call to railway management claiming stone fall on a track, a dead cow, a stalled car, etc will trigger a slowdown on that line, a call to the driver, and an inspection.
If that's not happening then management is playing fast and loose with legal responsibility and the risks of mass and inertia.
It's not about the possibility, it's about probability. People are posting more fake images and videos than ever before. More is categorically different.
