what is the minimum speed for a metra electric train to instantly kill you when hit

The lethality of a train collision is not solely dependent on speed; many factors come into play, including the weight and type of train, where the impact occurs on the body, and other conditions. However, it's crucial to understand that being struck by a train can be fatal at very low speeds due to the massive weight and momentum of the train. Even at speeds as low as 10-20 mph, the likelihood of serious injury or death is extremely high. It's important to always prioritize safety around trains and railway tracks, and to follow all safety guidelines to avoid accidents. If you have concerns about train safety, please reach out to relevant authorities or safety organizations.
