The gateman was at his post and it was his duty to lower the gates a reasonable time before the arrival of the train. There was testimony on behalf of plaintiff that the train approached at a speed of 30 miles an hour without giving any signal of its approach and that the gates were not seasonably closed. This is evidence of negligence on the part of defendant.
The question of how far a traveler may rely upon the fact that safety gates are open has been several times considered by this court. Woehrle v. Minnesota Transfer Ry. Co. 82 Minn. 165, 84 N. W. 791, 52 L.R.A. 348; Stegner v. Chicago, M. & St. P. Ry. Co. 94 Minn. 166, 102 N. W. 205; Flygen v. Chicago, M. & St. P. Ry. Co. 115 Minn. 197, 132 N. W. 10; Sumner v. Chicago & N W. Ry. Co. 122 Minn. 44, 141 N. W. 854; Wardner v. Great Northern Ry. Co. 96 Minn. 382, 104 N. W. 1084; Lang v. Northern Pacific Ry. Co. 118 Minn. 68, 136 N. W. 297. These decisions establish the rule that, where a railroad company supplies safety gates at a crossing which it is in the habit of closing as its trains approach, the fact that the gates stand open is an assurance of safety and an invitation to travelers to pass; that this is not, however, an unqualified assurance or invitation, for the traveler may not even then close his eyes and ears to danger. If he relies exclusively upon the assurance or invitation which is implied by the open gates, he is negligent. If he does not rely exclusively on such assurance, then the question is whether he exercises a degree of care that is reasonable under the circumstances, and that question must be one of fact for the jury, unless the facts leave the inference of negligence so plain that reasonable men could not draw differ
“Q. What seems to be the trouble with you, Miss Haugen? A. The back fail me and the right arm. The right arm is stiff. Q. And your back? A. Yes, sir. Q. Anything more? A. I got struck bad in the head. Q. Is your memory as clear now after this accident as before? Can you think as clearly ? A. I can’t hardly remember anything from one day to the other. Q. After this accident? A. No. Q. Could you remember things well before the accident? A. Yes, sir, for quite a long time. Q. Is that the reason why you can’t answer the question as clearly, because your head isn’t well ? A. That is the reason. Q. Was your head injured in this accident? A. Yes, sir. Q. You say your head has not been right since that time? A. No, it hasn’t been right. Q. You can’t remember clearly? A. No. * * * Q. I will ask you if you have any*58 headaches ? Oh, yes, most all the time. Q. Did you have trouble with headaches all the time before the accident? A. No, I had pretty good head. * * * Q. Can you walk as well now as you could before this accident? A. No, I can’t. Q. Why can’t you walk as well? What seems to be the trouble, if you can tell the jury ? A. My back and side pains me. Q. When you walk can you walk straight or do you have to limp a little ? A. I can’t walk straight.” Though she complained of loss of memory her memory of the facts surrounding this accident was very clear.
Other testimony goes somewhat more into detail but adds little to the above. From this alone the jury were asked to diagnose plaintiff’s physical condition, to make a prognosis of her future, and to determine the cause of her ailments. We are of the opinion that they could not reasonably do so. They could only speculate as to these important matters. In some cases medical or expert testimony may not be necessary in- order to enable a jury to determine the nature of an injury or its cause. In other cases such testimony is necessary to any intelligent understanding of the injured person’s condition and prospects. This seems to us such a case. In this case the jury could see that some injury was sustained, and the testimony would sustain a verdict in some amount. But we are wholly unable to see how they could fix her damages at any substantial amount. Courts must exercise much circumspection in sustaining large verdicts in cases where no injury can be seen, and where the word of the person injured is the only evidence of its extent. Johnson v. Great Northern Ry. Co. 107 Minn. 285, 119 N. W. 1061. Taking the evidence as its stands, we think the damages awarded were so clearly excessive and manifest prejudice and passion on the part of the jury. Plaintiff’s counsel in his brief says, “if this verdict is excessive, this court will reduce it to the proper amount.” The trouble here is that the evidence leaves us without chart or compass to guide us in arriving at any amount. The damages may not be too large. From this evidence we cannot tell; yet the burden of proof is upon plaintiff. We are of the opinion that a new trial must be granted without condition.
So ordered.
