Texas Pacific Railway Company v…
“ No doubt a certain amount of bumping and jerking is to be expected on freight trains, and, under ordinary circumstances, cannot be complained of. Yet, it can be avoided, if necessary, and when the particular and known condition of the train makes a sudden bump, obviously dangerous to those known to be on top of the cars, we are not prepared to say that a jury would not be warranted in finding that an easy stop is a duty. If it was negligent to stop as the train did stop, the risk of it was not assumed by the plaintiff. ”
