Which is more fatal? Head under wheels of train or truck

[Electric1]

Firstly, I am not going with these methods atm, just asking a question. I am also aware that they are considered unethical.
A train appears to decapitate your head, and a truck appears to crush it. Which one is more fatal, which has more potential to go wrong?

it's so hard watching gore
my guess would be train
but it's an uneducated guess

My money is also on the train. Trains are heavier and longer, so it would have higher probability I think.

Both methods are lethal since they posses the mechanical ability to either crush or decapitate the head. The important difference is the probability to be fully successful without mauling the body. Train since they're so heavy can successfully decapitate the head at any speed even as low as crawling speed. Unlike trucks the trains direction is very linear and thus more easily executed.

The truck require more speed to be successful and is obviously not guided by rails, the possibilities of something going wrong is significantly higher then train.

Both works in theory but requires almost robotically determination and precision to succeed in the manner I'm describing. But since we are talking about a hypothetical scenario of an highly unethical way to ctb it doesn't matter.

I prefer the train
