Second, that the railroad violated the Safety Appliance Act in one of the ways claimed by the plaintiff as stated in these instructions. Third, that the [plaintiff's injury] [decedent's death] resulted, in whole or in part, from a violation of the Safety Appliance Act. If you find from your consideration of all the evidence that each of these propositions has been proved, then your verdict should be for the plaintiff.
