No, I think the train crews respect speed. You can be fired if you.... If you come back with a train, one of the first things they can do is download the data from the event recorder to compare it with the allowable speed on the track and see if they were speeding. Usually train crews do respect speeding. It's never been an issue, as far as I'm concerned.
