The verdicts were rightly ordered, because the evidence would not support a finding that when the deceased was injured he was in the exercise of due care. Such a finding would be only a conjecture. No one saw him at the time of the accident. If we assume that he was hurt by coming in contact with the switch, the evidence does not disclose how or why he struck it, or what he was doing at the time. When last seen before the accident he was walking upon the ground sixty feet or more from the switch, with a lantern in his hand going away from the switch and towards the rear-car of four box freight cars which were approaching the switch and approaching the deceased, and upon which he was expected to ride to another switch which it would be his duty to turn. The only witness who saw him was upon the top of the rear car, and this witness testified that the deceased came walking up to get a ride on that car ; that he did not see the deceased get on, but knew he was going to. get on because he came right over to the car, and that when he last saw him he was approaching the car with his lantern in his hand. When the car was opposite the switch the witness heard a “ bang,” the switch shook, and the light on the top of it went out. When about ten or twelve feet farther along, the forward trucks of the rear car went off the rails, and the witness laid down and looked backward, and saw a light in the middle of the track. He then jumped off the car, went back, and found the deceased, with his lighted lantern on his arm, fatally injured on the track, at a point ten or twelve feet from the switch, and on the opposite side of it from the point where he was last seen before the accident. The additional fact, that the board of the switch was found to be split and its frame bent, makes it probable that the deceased, having got upon the car, was carried against the switch, but even this is uncertain. There was no ladder on the side of the car, and there was a stirrup and a grab-iron on the right hand side at the front end. There was a similar stirrup and a grab-iron on the left hand side of the car at the rear end, and there was a ladder on the right hand side of the *481front end of the car, and another ladder on the left hand side of the rear end. Whether the deceased had got on board of the car, or, if we infer that he had, how he did so, and in what position he was when injured, can only be conjectured. It was for the plaintiffs to show by affirmative proof that he was in the exercise of due care, and because the evidence left it to conjecture, the verdicts for the defendant were rightly ordered. Besides this, the deceased had assumed as an ordinary risk of his work the possibility that, when boarding freight cars or riding on them, he might come in contact with switches or structures near the tracks. See Bell v. New York, New Haven, Hartford Railroad, ante, 443, and cases cited. The switch had long been in the same location, he had passed it many times a week for months, and the mere fact that after the accident the switch was found bent toward the track was not evidence that it was out of plumb before the deceased came in contact with it.
The evidence that a switch of a different kind was substituted after the accident was properly excluded. Precautions subsequen tly taken are not competent to show that the defendant was negligent before. Shinners v. Proprietors of Locks & Canals, 154 Mass. 168. Menard v.
