Employee was opening rail cars and when he went to open a rail car, he started to open the car and felt a pull in his back. Normally the cars are empty when the employees go to open the doors. The employee asked another employee to look inside from the top to see if it was jammed and that is when it was found that the rail car still had approx. 30 Ton of rock inside.
