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.
Or the trolley potentially carrying dozens of people falls over, killing and injuring more people than would have been otherwise.
going over people also soulnds like it would cause a derilment
