As someone who has trained Engineers for several years, I can say that there has been times Management has not listened to me and put someone I didn't feel was ready to be cut loose into the cab of a locomotive just to fill a position. This goes for Conductors too. Several times people right off the street were run through a class and put out in the field before they should have. Put an inexperenced Conductor with a poor performing Engineer and it's easy to have an accident or fatality. I know, I have witnessed it before and investigated incidents several times. Until railroads change their thinking, and put railroaders that care into management positions, this sort of thing will continue to happen.
