“ We do not need to inquire whether a different conclusion would follow if the conductor in the caboose had discovered that the engineer had gone upon the main track through a misunderstanding of a later order, and, discovering this, had failed after a substantial interval of time to give warning of a peril that he could have easily averted. Nothing of the kind appears. There is an absence of the essential factors that wake into life the doctrine of the last clear chance. In the first place, the conductor did not know any more than Simpson did that an order had been violated. ”
