A train wagon easily weights 20 tonnes and more. If it goes just at 50 kph, it has an impulse of 278.000 kg*m/s. Respectively 278.000 Ns. According to some googling human bones tend to break at around a force of 4.000 N.
Realistically the train is just going to flatten whatever flesh and bones are between the wheel and tracks.
