I'm thinking of parking my car on the train track
It's very dangerous, why would you park it within the train tracks?
I want to stop the next train, the train is going to hit my car
Are you feeling okay? It's not normal to want your car to hit the train. There will be serious damage and injuries to you, the car, and your train. If you are feeling down, do you think you can see a therapist instead?
No, I need my car to be hit.
I don't think your car needs to be hit, I think you need to be safe and sound. Would you want to have lots of medical and auto repair bills to take care of afterwards? I still suggest you try to talk out anything you're having a problem with.
