Opinion by
Mr. Justice Stewart,The action was for the recovery of treble damages under the Act of June 4, 1883, P. L. 72, for injury alleged to have been sustained in consequence of the defendant’s refusal to furnish a siding connection with a coal mine operated by plaintiffs under a lease. Application for the siding connection was made 11th September, 1902. Some time thereafter the defendant submitted to the plaintiffs a plan, dated 4th October, 1902, showing a proposed siding which, so far as appears, was acceptable to the plaintiffs. Plaintiffs were proceeding with the opening of the mine when on the 14th November they were notified by the defendant that their application for a siding connection was declined. The claim was for damages sustained between January, 1903, when plaintiffs were prepared to ship coal, and August, 1904, when the New York Central Railroad Company by right of eminent domain appropriated the land which plaintiffs had intended for their siding. A verdict resulted to the plaintiffs in the sum of $34,814.50, single damages, afterwards reduced by remittitur to. $27,851.60, and then trebled by the court. The appeal is from the judgment so obtained.
It is complained first of all that the court held as a matter of law that the right of action was in the plaintiffs. That plaintiffs were the original lessees of the mine was undisputed. Subsequent to the demand for a siding connection, the White Oak Coal Company, a corporation, was created, in which these plaintiffs were the principal shareholders; and 5th November, 1902, a verbal agreement was entered into providing that when two drifts in the mine were opened to marketable coal, plaintiffs were to transfer the lease to the corporation *30for the consideration of $10,000.00 in the capital stock of the corporation. It was not until 12th January, 1905, that the contract was fully performed by the transfer of the lease and the payment of the purchase price. Meanwhile the corporation in its returns to the auditor general of the State, during the years in which one of the plaintiffs was president of the corporation and the other its treasurer, the reports being certified by them as such officers, represented that the mine was the property of the corporation. Appellant contends that on this evidence it should have been submitted to the jury to determine where the ownership of the mine was during the period for which damages were claimed. Manifestly the defendant had no other concern with respect to the question sought to be raised than to protect itself from a second suit for the same cause of action. It is not disputed that up until 12th January, 1905, no matter what control meanwhile the corporation exercised over the mine, and however it made its reports to the auditor general, the legal title to the mine was in the plaintiffs. No assignment or transfer of the lease until then had been made and no part of the purchase price had been paid. This being so, the defendant was without reason to be concerned. A recovery by plaintiffs on their legal title would have been a conclusive bar to another action by any one. The law applicable to such case is very clearly stated in Armstrong v. Lancaster, 5 Watts. 68. Gibson, O. J., there says: “A legal title is certainly sufficient for. the maintenance of an action, excepting, perhaps, where the Commonwealth stands as a trustee in an official bond; and there it may be necessary to. show a particular injury as a title to her interference) in order to secure the obligor from an officious intermeddling.......The court will undoubtedly search out the actual plaintiff, where it is necessary, and fix on him the responsibility of a party, by subjecting him to costs, a plea of set off, or any other liability that may be necessary to *31protect the defendant ; but here, where a recovery on the' naked legal title would have been a conclusive bar to another action by any one, to set out the equitable title in t the declaration was unnecessary. The equitable owner of a right of action can recover on the legal title only; and any one attempting to use it a second time would be repulsed at once by a plea of former recovery. Of all the parties concerned the ostensible defendant had least to do with the equitable ownership. But there may be adverse claimants of it; and how are the rights of a party not named in the record to be protected? Certainly not by preventing a recovery and extinguishing the expectations of himself and every one else. If this judgment were affirmed the party who maintained the contest, under the defendant’s shield would have concluded himself, as well as his competitor. What then was his most available course? Obviously to lie by till recovery or to promote it; then to arrest the money in the sheriff’s hands by notice not to pay it over, rule it into court, and move for leave to take it out. This done, the pretensions of the claimant could be determined by the court, or a jury, under an issue, as the case might require.”
The action of the court in refusing to sustain defendant’s contention with respect to this feature of the case stands clear of error.
That the refusal to allow plaintiffs a siding connection was an undue and unreasonable discrimination against them was too clearly established to admit of question. The congested condition of traffic on defendant’s road, which was offered in explanation, afforded neither excuse nor extenuation. The means of protection against such condition was in defendant’s own hands. It was under no duty to haul more coal than could safely and conveniently be transported over its line; but a bounden duty did rest upon it, in limiting the amount to be accepted by it, because of extraordinary conditions, to show no preference as between shippers, *32and to treat all alike on some equitable basis.' It was a , period of shortage of car supply, and the defendant had adopted a basis of car distribution, a pro rata, based on the productive capacity of the mines. To prevent the opening up of additional mines from increasing the total traffic, a simple reduction of the rate would have been entirely sufficient to that end, and all that plaintiffs were entitled to was to share ratably with others similarly situated in the rate so established. Several points were submitted on behalf of the defendant, asking for instructions to the contrary of the view here expressed. The refusal of these points has been made the subject of several assignments of error. Further discussion of them is unnecessary.
The evidence with respect to sale of cars by defendant to individual shippers had no relevancy to the issue being tried. No more had the evidence with respect to the loading of cars from wagons. All of this evidence should have been excluded, but it is impossible to see how it in the remotest way entered into the final conclusion. Otherwise, it would be ground for reversal.
There was no error in not distinguishing between inter-state and intra-state commerce in this case. It was not incumbent upon the plaintiffs to show what proportion of total tons they would have sold within the State. The case called for no such distinction.
The case of Robbins v. Farwell, 193 Pa. 37, furnished a complete answer to appellant’s contention that it was not for court but for the jury to say whether there should be a recovery for treble damages. Here they were trebled upon a rule to show cause. No question is made as to the verdict having been for single damages strictly as directed by the court. This was exactly the situation in the case above cited, where in affirming the action of the court in trebling damages upon rule, this court said, speaking by Dean, J., “Ever since Welsh v. Anthony, 16 Pa. 254, decided in 1851, the trial courts have exercised the power of doubling or trebling the *33damages, or refusing so to do, when it clearly appeared by single damages only were found by the jury, and this court has in a number of cases since Welsh v. Anthony, supra, recognized the authority.”
The verdict for single damages was conclusive as to the question of undue and unreasonable discrimination. This left nothing to be considered by the jury in connection with the trebling of the damages. The statute made provision for that. This brings us to the consideration of the only matter remaining.
The facts of the case indicated very clearly the true measure of damage. During the period for which damages were claimed plaintiffs’ mine was idle, and wholly unproductive because of the denial of siding connection. In January, 1905, the White Oak Coal Company then being in possession of the mine, a siding connection was furnished and the latter company then began and continued its operation of mining and marketing the coal from the mine. The plaintiffs offered evidence to show, 1st, the productive capacity of the mine; 2d, what the market price of the coal was month by month during the period of their trial of it; and, 3d, the market price for a corresponding period of seventeen months next following when operated by the White Oak Coal Company. By this showing, the- price had gradually declined, and the claim was for the difference in market price. Had this measure been strictly observed there would have been but little ground left for the contention. The court’s instructions to the jury on this branch of the case were as follows: “Now upon the subject of how much coal could have been mined and shipped there is a wide difference of opinion between the witnesses for the plaintiff and for the defendant.......You must satisfy yourselves from the evidence upon this subject with reasonable certainty as to the quantity of coal which might have been mined and shipped, considering all the existing conditions, the difficulties of mining, the water, the rolls in the vein of coal which would delay and make *34the mining expensive, and the difficulty in obtaining car supply:; you must satisfy yourselves from all the evir dence with reasonable certainty as to the quantity which might have been mined and shipped during that period.......You may be aided in that inquiry, gentlemen, by the rating placed upon the capacity of this mine by the defendant company. You will have a tabulation of the rating of the mine at different periods with you. At an early period in the history of the mine, as we recall it, it was rated as having a capacity of three cars a day; you will consider that in ascertaining the quantity which might have been mined and shipped from this mine. You will consider the market price prevailing during the various months when the plaintiffs claim they could have mined and shipped this coal if the siding had been allowed them and the market price prevailing after the time when the sidings were made and shipments were actually permitted and the difference in the market price upon that quantity of coal would be the measure of compensation to which these plaintiffs are entitled, in case you find there was an undue and unreasonable discrimination which they allege.”
How widely the jury departed from the measure here given them, is made very apparent by the learned trial judge in his opinion overruling defendant’s motion for a new trial, on condition of a remittitur being filed by plaintiffs. He there demonstrates how the jury arrived at their estimate of plaintiffs’ loss by taking as a factor the productive capacity of the mine instead of the amount of coal they could have marketed therefrom. He says: “The uncontradicted testimony in this case shows that in this region there has always been an insufficient car supply even when the coal trade was in normal condition. This arose not from any discrimination in car distribution, but from an insufficient number of cars to meet the demands and rated capacity of the mines. There is neither allegation nor proof of discrimination against the plaintiffs in the distribution of the *35cars. It seems to us, therefore,- that it is reasonably certain that plaintiffs would not have been able in 1903 and 1904 to secure sufficient cars to carry to market Mr. Lawton’s estimated quantity of coal, and thus the plaintiffs’ estimated sales would have been further diminished. The jury does not appear to have made any deduction whatever from Mr. Lawton’s estimation either for reasonably certain delays and difficulties in mining, nor for the reasonably certain impossibilities of procuring the cars necessary to carry the estimated mine product.”
The verdict was for single damages. The court directed that upon plaintiffs’ filing a remittitur of all excess over $27,851.60, the rule for a new trial should be discharged; and this was accordingly done. This action of the court is assigned as error, and it is contended that the verdict even as reduced by the remittitur is excessive. That the verdict as rendered was in excess of the plaintiffs’ just demands was fully demonstrated by the learned trial judge in his opinion refusing a new trial. It would seem the better practice in cases of this kind, when it clearly appears that the jury in reaching its verdict overlooked items or circumstances making in relief of the defendant pro tanto, and which they were directed by the court to consider, but which in themselves furnished no fixed standard for admeasurement as to value, to grant a new trial; but we have no fixed rule' requiring it. It is within the discretion of the court to adopt either of two methods of correction: It may grant a new trial outright, or it may grant it on condition that plaintiff refuses to remit so much of the verdict as the court concludes is excessive. Here the latter course was adopted, the court fixing the amount to be remitted which it estimated to be the full equivalent of those matters making in relief of defendant which had been overlooked. This was no more than saying that had the verdict been for this reduced sum the court would have approved it, and a new trial would have been *36refused. Plaintiffs filed the remittitur, and defendant was protected to that extent by the interference of the court. With this determination of the case we would not interfere were it not that it seems to us apparent from the record that the learned judge in calculating what would be the equivalent of those matters making in relief of defendant, and which had been overlooked by the jury, -notwithstanding he had specifically directed attention to them, failed to give consideration to the evidence 'in the case which seems to have been introduced by the plaintiffs showing the car supply that plaintiffs would have been entitled to receive during the period for which damages are claimed according to the rate of distribution adopted and based on the productive capacity of their mines. We must assume that this evidence was overlooked rather than disregarded for insufficiency, inasmuch as it is not commented upon in any way. The learned trial judge rightly held that the difference in the market price of the coal plaintiffs could have mined and “shipped” had a siding been allowed them, and the market price of such coal after the time the siding was allowed, would be the measure of compensation. Plaintiffs were without cars of their own, and for the shipment of their coal would have been entirely dependent upon the defendant company ‘ for a supply. It being a period of car shortage plaintiffs could claim only the same proportion of those owned and controlled by the defendant as was allowed to other shippers, based on the productive capacity of the several mines. If there was evidence that an equitable rate of distribution had been established — and from our examination of the record we think there was — such rate would be a fixed factor in the case for the determination of the amount of coal that would be shipped. The fact that the amount of remittitur ordered by the court is so much less than it would have been had the rate of car distribution been considered, is 'to our mind convincing that the evidence touching this matter was overlooked, *37with, the result that we have here a judgment based on the productive capacity of the mines, whereas only, so much of the coal could have been marketed as would have been accommodated in the cars which plaintiffs could rightfully have demanded of the defendant. A hew trial of the case ought not to be necessary, but however this may be, what for the present we must regard as a manifest injustice to the defendant calls for correction, and a reversal of the judgment is therefore required, only however that the motion for a new trial in the court below may be reinstated, which is now ordered to be done, the case then to be proceeded with and such action taken thereon as law and justice may require.
The judgment is accordingly reversed, and motion for a new trial reinstated.
