Trains are engineered to absurdly high safety standards and every time there is a crash, it's widely publicized and an in-depth investigation is required along with suggestions for systemic changes to prevent repeat events, and the companies are required to pay large settlements:

At the same time, trains are vastly safer than personal cars. Yet when a driver kills someone, police can barely be bothered to attend the scene and rush to excuse the driver and let traffic flow again.
The safety standards on vehicles are such that billions are spent on engine development yet we tell people to watch out for the "blind spot" in that trucks mirror contraption. We're soon going to have autonomous driving AI yet trucks are roaming city streets that are unsafe by design and regularly claiming lifes. I don't see Volvo and MAN settling with anyone over that.
