If the action against the company is based upon the first ground, it is apparent that the fact that the engineer was guilty of negligence in the running of the train which would constitute a cause of action against him, would not alone show a violation of duty on part of the company. If based upon the liability created by the statute, it is equally clear that the ground of action is distinct and separate from that charged against the engineer. Under the allegations of the petition, in order to entitle plaintiff to recover against the defendant Emsley, it must be shown that he him- selfwas guilty of negligence in the management of the train under his charge, resulting in injury to the deceased. Failing in proof of personal negligence on part of the engineer, plaintiff could notre- cover against him, but that would not entitle the company necessa- rily to a verdict in its favor. In the petition it is expressly charged that the defendants, "while operating and running a passenger train over the defendants’ road, did carelessly, negligently, and wrong- fully run said train of cars upon and against Alvis Fink." In legal effect, this charges that the defendant company negligently and care- _ lessly ran said train of cars; and, under this allegation, it is open to plaintiff to show negligence on part of any employe of the company in the running of said train; and if negligence on part of a flagman, or on part of the conductor, train dispatcher, or road-master, in con- nection with the running of said train, could be proven as a matter of fact, and that such negligence was the proximate cause of the death of deceased, then the plaintiff could recover against the company, but _ not against the engineer. Under the averments of fact in the petition, two controversies are presented,—one between plaintiff and the defendant Emsley, and one between plaintiff and the defendant company. In the controversy between plaintiff and Emsley, the company has no part nor lot. It has no legal interest therein; and, if the plaintiff and Emsley were citizens of diiferent states, the latter could remove the action, even if the company and plaintiff were citizens of the same state. In the controversy between plaintiff and the company, Emsley has no legal interest. The cause against the company not only can be separated, but must be separated, from that against Emsley, because the grounds of liability are legally different. Although the case may be tried as one before the same jury, the issues upon which the liability of the
