was badly obstructed. Other facts will be set out in the course of the opinion.
Jurisdiction, based upon diversity of citizenship, is established.
The complaint asserts that defendant was guilty of negligence which proximately caused plaintiff’s injuries. Defendant admitted jurisdiction and the fact of collision but denied all allegations of negligence and affirmatively alleged that plaintiff’s injuries were caused by his own negligence. Plaintiff suffered severe injuries as a result of the collision, including permanent brain injuries. The amount of damages is not here attacked.
The court submitted to the jury the issue of defendant’s negligence, proximate cause, plaintiff’s contributory negligence and the issue of damages in event the jury found plaintiff entitled to recover. The pleaded specifications of negligence submitted to the jury were:
“1. Failing to signal the approach of the train by sounding a whistle and continuously ringing a bell in violation of § 478.19 of the Iowa Code [I.C.A.],
“2. Failing to operate the train at a speed which was reasonable and in accordance with due care under the circumstances then and there existing just prior to and at the time of the accident.
“3. Failing to maintain proper warning devices at the crossing in question.”
Defendant by motion for directed ver•dict made at the close of the plaintiff’s evidence and renewed at the close of all the evidence challenged the sufficiency of the evidence to support each allegation ■of negligence submitted and also urged that plaintiff had not met the burden imposed upon him to establish freedom from •contributory negligence. Defendant also incorporated its attack upon the sufficiency of the evidence to support a verdict ~by exceptions to instructions and by motion for judgment n. o. v.
Defendant as a basis for reversal relies upon the following points:
I. The court erred in submitting the issue of whether plaintiff was entitled to the benefit of the Iowa “no eyewitness rule.”
II. Contributory negligence on the part of plaintiff has been established as a matter of law and hence the court erred in overruling defendant’s motions for directed verdict and judgment n. o. v.
III. The court erred in submitting each of the three specifications of negligence heretofore set out to the jury for the reason that there is no substantial evidence to support any of the specifications.
IV. The court erred in submitting the sudden emergency instruction.
I.
By Instruction 16, the court submitted to the jury the issue of whether there was an eyewitness to the accident under the Iowa no eyewitness rule, and then properly instructed the jury as to the applicability of such rule in event the jury found there was no eyewitness. Defendant excepted to such instruction on the ground “that there was an eyewitness to the accident in question, and there is no justification for giving the instruction nor for the application of the no eyewitness rule.” On brief, defendant asserts Instruction 16 should not have been given the jury for the following reasons:
“(1) there is no precedent in Iowa law for the application of this rule in a railroad crossing accident case;
(2) the physical facts of this case clearly indicate that the plaintiff failed to exercise due care at and prior to the railroad crossing in question;
(3) Engineer Jesse Worth was an eye witness in this case and, therefore, the rule has no application.”
Defendant’s first contention is without merit. The no eyewitness rule is well-established in Iowa jurisprudence and has been extensively discussed in many cases, among them, Mast v. Illinois Central R. R., D.C.Iowa, 79 F.Supp. 149,164-173; Chicago, R. I. & P. R. R. v. Lovejoy,
