Opinion by
Mr. Justice Mitchell,The plaintiff’s husband was engineer of a train which was derailed by a subsidence of the track, and he was killed. The defense was his own contributory negligence.
It appeared by the undisputed evidence that the track was laid for a considerable distance over mine workings from which the coal had been removed; that from time to time prior to the accident there had been cavings in of the surface along the railroad’s right of way; that the road was known to be in an unsafe condition from this tendency, and that the accident resulting in deceased’s death arose from this cause. On the argument several points were made by appellant in regard to deceased’s contributory negligence, but we do not find it necessary to notice any but one.
The recognition of the dangerous condition of the track was such that the company had begun a change of location, and pending the completion of the work had posted a notice on the bulletin board of the assistant train master’s office for nearly three weeks before the accident that “ All trains will run slow between Sugar Loaf Switch and South Sugar Loaf, account track settling.” It was the duty of deceased to examine this bulletin board before starting and at the end of each run, that is, six times every day that the notice was up,- and the inference *613is irresistible that he must have seen it. But beyond this there is the positive testimony of the fireman that the deceased had a copy of the order which he showed to witness. There was further evidence that running slow meant eight to ten miles an hour, and that at that speed the accident would not have happened, or at most would not have had any serious results.
It is true that an effort was made by plaintiff to show that the notice was not posted until after the accident, but the evidence could hardly be said to amount to a scintilla. A single witness, the engineer of a shifting engine, was called to this point in rebuttal, but his testimony cannot fairly be said to go further than that he did not see the notice until after the accident.
It is further said that the testimony as to the posting of the notice and the deceased’s knowledge of it was by witnesses for the defense and their credibility was for the jury. Such certainly is the general rule. The jury are not bound to believe every story that a witness or witnesses are willing to swear to simply because no other witness contradicts it. If its inherent improbability or irreconcilability with facts shown or admitted are such that it does not command their assent, the jury may disregard it. But this rule is founded on common sense and knowledge of human nature, and must be limited by the same standards. When the testimony is not in itself improbable, is not at variance with any proved or admitted facts, or with ordinary experience, and comes from witnesses whose candor there is no apparent ground for doubting, the jury is not at liberty to indulge in a capricious disbelief. If they do so, it is the duty of the court to set the verdict aside. Such cases are exceptional, but this is one of them. The fact that the notice was there for three weeks in a place where it was the daily duty of the deceased to look, was not denied except inferentially by one witness; the coemployees of the deceased saw it, and when the fireman testified that the deceased had shown him a copy of it, he merely added positive testimony to what was already an irresistible inference from facts previously proved. The verdict should have been set aside as in direct disregard of the evidence, and where that is the case, the court may refuse to submit it at all and direct a verdict accordingly: Holland v. Kindregan, 155 Pa. 156.
*614On a review of the whole evidence the facts are practically undisputed and from them it clearly appears that Lonzer’s death was the direct and proximate result of his voluntary disregard of an order of the appellant made specially to avoid the very danger from which the accident resulted. Under such circumstances there could be no recovery by him or by anybody claiming through him.
Judgment reversed.
