Opinion by
Head, J.,The defendant, in the exercise of its right of eminent domain, had appropriated a portion of the land of the plaintiff and constructed thereon a branch line of its railroad. After a jury of view had assessed the damages an appeal was taken to the court of common pleas, and from the judgment on the verdict rendered in that trial this appeal was taken. There was evidence tending to show that the damages suffered by the landowner resulted chiefly from the operation, of the railroad under existing conditions rather than from the taking of the strip of land on which it was constructed. There was also evidence tending to show that the chief business of the branch fine was in the transportation of coal from lands in the vicinity of the plaintiff’s property. Against the objection of the plaintiff the court received evidence to show the physical extent of the coal vein there operated and that it was small in area. The manifest purpose of such testimony was to convince, the jury that the coal would soon be exhausted, and as a consequence that the operation of the branch line complained of would not continue for any great length of time. We think such testimony, directed as it was to physical conditions, was relevant to the inquiry before the court and was therefore properly received. The first assignment is dismissed.
*616The line of the railroad as it crossed the plaintiff’s land was located within a few feet of the derrick of an oil well operated by the plaintiff from which he derived a certain revenue. Again the learned trial court, over the objection of the plaintiff, permitted the defendant to show that the quantity of oil produced from this well was steadily diminishing. This again was a physical fact, calculated to place before the jury the conditions that actually existed and thus to enable them to arrive at a just conclusion as to the real value of the plaintiff’s property and the extent of the injury he suffered. The second assignment is dismissed.’
The fourth assignment alleges error in permitting a witness for the defendant to give his opinion as to the length of time during which the company would use its branch line and when it would be abandoned. Of course, any such opinion or estimate of time by the witness would be in no way binding upon the company. Having appropriated the land for railroad purposes, its right was to continue such use indefinitely, and the plaintiff’s damages could not fairly be lessened because of the opinion of the witness that the right would be abandoned within a short period of time. But as we understand the record, this testimony, on motion, was stricken out. Whilst such action does not always furnish a complete remedy for the injury done to a party by the receipt of incompetent or inadmissible testimony, there would remain no sufficient cause for a reversal unless it appeared to us that the hurtful impression produced on the minds of the jury by hearing the testimony complained of had not been obliterated by the subsequent action of the court. Whilst therefore we might be unwilling to reverse the judgment upon this assignment alone, as the case must go back for retrial for another reason, we think it proper to declare that the testimony complained of should have been excluded.
The fifth and sixth assignments complain of the charge of the court as to the general lines upon which the jury *617were to determine the extent of the damages suffered by the plaintiff. A careful reading of the excerpts on which the assignments are based, and indeed of the entire charge, leads to the conclusion that in the main the learned trial judge proceeded on the correct theory, and we are unable to perceive anything in the extracts specially complained of in the two assignments named that could justly be considered erroneous. These assignments are therefore dismissed.
Upon the cross-examination of the plaintiff he was compelled to testify, over the objection of his counsel, the price -at which he succeeded in selling the coal under his own land and that he obtained for it a larger price than that received by some of his neighbors. This fact was permitted to go to the jury and' they were subsequently instructed that they might properly consider it in making up their verdict although the plaintiff further testified, and in this he was not contradicted, that at the time he sold his coal the railroad was not there and had not yet been located. It seems to us manifest that the particular price at which the plaintiff was able to sell his coal might depend on many factors other than the location of the railroad. It might be fairly attributed in large part to his own native shrewdness in making a favorable deal; it might have been that the natural location of his property made his tract of coal especially valuable or desirable as compared with -other tracts in the same field. There are many other like illustrations that could be offered, all of which point to the propriety of the rule that the selling price of a particular piece of property is not evidence of the general market value with which alone juries are to deal in cases like the one before us.
In Pitts. & Western Railroad Co. v. Patterson, 107 Pa. 461, Mr. Justice Clarke thus stated the true rule on the subject, viz.: “The location of the land, its uses and products, and the general selling price in the vicinity are the data from which a jury may determine the market value. The price which, upon a consideration of the matters *618stated, the judgment of well-informed and reasonable men will approve is the market value. A particular sale may be a sacrifice compelled by necessity, or it may be the result of mere caprice or folly; if it be given in evidence it raises an issue collateral to the subject of the inquiry, and these collateral issues are as numerous as the sales.” To the same effect are the cases of Pitts., Va. & Charlestown Railway Co. v. Vance, 115 Pa. 325; Curtin v. Nittany R. R. Co., 135 Pa. 20, and Becker v. Phila. & Reading R. R. Co., 177 Pa. 252.
Applying the principle of these decisions to the case before us we cannot' escape the conclusion that the learned trial judge fell into error in admitting the evidence referred to and instructing the jury that they might properly consider the price at which the plaintiff had sold his coal in making up their estimate of the damages sustained by him from the construction and operation of the railroad. The third and seventh assignments are sustained.
Judgment reversed and a venire facias de novo awarded.
