Opinion by
Mr. Justice Stewart,This appeal is from the order of the court refusing a motion for judgment for defendant non obstante veredicto. The *99facts as established by the finding of the jury are these: The plaintiff was one of some twenty-five workmen employed about a construction train in the work of loading and unloading gravel along the line of the defendant’s roadbed. The train consisted of some six or eight open cars, and was in charge of a conductor. On the morning of the accident, the cars having been loaded and the train being about to proceed to the point for the distribution of the gravel, the workmen were directed by their foreman to get aboard the cars and begin the work of unloading, when the train stopped. The plaintiff took his position on the car farthest from the engine. After proceeding about 500 yards on the main track, the train came to a stop on the signal of the foreman, and the plaintiff at once proceeded with his wmrk. While in the act of sticking his shovel into the gravel the train suddenly, without notice or warning, and within a moment after it had come to a rest, again started with a severe jolt, which threw plaintiff overboard. In the fall, and what resulted directly therefrom,' he sustained serious injury. As the case was submitted to the jury, on the theory that the facts would, be found to be as testified by the plaintiff’s witnesses, negligence in the matter of starting the train was assumed, and the only question was, whose was the negligence? One of the plaintiff’s witnesses testified that the train started upon the signal of Hounslow, who was a foreman; all the others testified that the signal was given by a Mr. Potter, who the evidence shows was supervisor of the work of repair, and Hounslow’s superior. The learned trial judge made it very clear in his charge to the jury, that no liability would result to the defendant from any negligence of Hounslow in this connection, inasmuch as being a fellow employee with the plaintiff, the latter must be held to have assumed all such risks in the course of his employment. He held, however, and so instructed the jury, that if the train started on a signal given by Potter, the defendant company would be liable in this action, for the reason that Potter stood in the relation of vice principal, and that what he did must be regarded as the act of the company. The finding of the jury was that Potter gave the signal, not Hounslow. In our view of the case, it is immaterial whether Potter be regarded a fel,low employee with plaintiff or a vice *100principal; the result must be the same in either case. If the former, of course no liability attached to the defendant for his act for the reason stated by the court; if the latter, the same result must follow, but for a different reason. How inconclusive, with respect to the main question in the case — the negligence of the defendant company — the finding of the jury that Potter gave the signal for the train to start, was, is made apparent by an examination of the evidence. Potter is shown to have been at the time of the accident supervisor of this particular construction' work, but there is not a particle of testimony that connects him, even indirectly, with the operation and movement of the train. He is not shown to have been on or about the train the morning of the accident; nor does it appear that his duty required him to accompany the train at any time. It was his business to indicate the places along the line of the road where the gravel was to be unloaded, where the train should stop for this purpose, and to what point it should proceed; but the actual movement of the train, the starting and stopping the machinery that produced the movement, these were matters of detail -with which he is not shown to have had anything to do. In the absence of all evidence to the contrary, it is to be supposed that authority with respect to these was committed to the conductor in charge of the train. On this particular occasion the train, after running about 500 or 600 yards from where the gravel was loaded, had stopped short of the place where Potter wanted it discharged. He was at that time 115 yards away, and was seen by plaintiff’s witnesses to signal for the train to advance further. It was the sudden starting of the train, following the signal from Potter, that occasioned the accident; but where was there any negligence in what was done by Potter in this connection ? If the train was not where it should be for purposes of unloading, he was strictly in line of duty in requiring it to proceed further. In communicating his order to this effect to those in charge of the train, it is not pretended that he adopted any unusual or unreasonable method. Whether the signal was given to the conductor of the train or to the engineer does not appear; nor does it appear whether or not any intermediate order was given. All that the evidence discloses is, that the movement of the train *101followed, immediately upon Potter’s signal. The sudden and violent starting of the train without warning, under such circumstances as we have here, might well be regarded as a negligent act; but how is it possible to derive from the facts of the case any duty resting upon Potter to give such warning? How could he have done it except by proceeding to where the train was ? If a vice principal, he had a perfect right to assume that those in charge of the train, whose duty it was to obey the signal given by him, would act with ordinary prudence in carrying it out: Hoover v. Railway Company, 191 Pa. 116. The customary way of giving warning in such cases, as we all know, is by bell or whistle, both of which were under the immediate control, in this case, of the engineer. If additional warning is required at any time, it is only natural to expect it to come from the conductor in charge of the train. It is so obviously the duty of these particular employees to see that accustomed signals are given when occasion calls for them, that there is no escape from the conclusion that for the failure to give such warning hero, upon one or both must rest the responsibility for what resulted from the omission. Potter, as we have said, had a right to expect that such warning would be given; his duty did not require him to go to the train to see that it was given. The result of the verdict was to charge the responsibility upon Potter, without a particle of evidence from which an inference could be drawn that what he did in the matter was negligently or improperly done, or that he omitted anything that was his duty to do. Had he been a mile away when he gave the signal, it could not have been pretended that it was incumbent upon him to see that warning was given before starting the train. The fact that he was only 115 yards from the train when he gave the signal affects only the practicability of his giving the warning, and not his duty in this regard. We are not to be understood as conceding that he was a vice principal; we have assumed it only to show that were this a fact in the case, the evidence would not warrant a recovery. It discloses no negligence for which the defendant was responsible.
The order discharging the rule for judgment non obstante veredicto is reversed, and record is ordered to be remitted for the court below to enter judgment in accordance herewith.
