after stating the case as above, delivered the opinion of the court.

The section of railroad between Newcastle and Rifle Creek upon which the collision occurred was the railroad oí the intervener, the Denver Company, and in its possession and use at the time of the collision. The so-called “lease,” as interpreted and acted upon by the parties to it, gave to the Midland Company trackage rights for its trains over this section of railroad, upon the terms agreed upon. The appointment of a joint superintendent to control the movement of trains and engines over that section and the adjoining section to Grand Junction, also used in common by the two railroad companies, with authority to employ subordinate train dispatchers, " *242was a proper provision to insure the care necessary to prevent collisions, while obtaining the fullest use of the single track by both companies; and it was matter of convenience to intrust supervision over the condition, repairs, and improvements of that division of railroad to such superintendent. As each company operated its own trains by its own servants in the prosecution of its own separate business, in which the other company had no interest, the use by each company was in common with the other company, and not a joint use; and each company, in the operation of its trains, was bound to use reasonable care, under the circumstances, to avoid injury to the trains of the other company. The findings of the special master as to the practice in the settlements for live stock killed on the line between Newcastle and Grand Junction were not immaterial, as they tended to show the practical interpretation of the so-called “lease” by the parties, and the character of the actual possession and use of that section of railroad.

The receiver had taken the place and assumed the rights and obligations of the Midland Company in respect to that section of railroad, and was, as receiver, responsible to the Denver Company for all the damages sustained by that company from the said collision and the explosion of gas and conflagration which immediately resulted therefrom; such collision being caused wholly by the negligence of the servants of said receiver in the management of the said freight train. As the Denver Company then owned, possessed, and operated with its own trains the railroad between Newcastle and Bifle Creek, on which this collision occurred, it was liable to its own passengers, and to the owners of property carried by it on its passenger train, for injuries and losses from the collision, explosion, and fire, though caused wholly, as aforesaid, by the negligence of the receiver’s servants while running his freight train upon that section of railroad with the permission of the Denver Company. Railroad Co. v. Barron, 5 Wall. 91, 104. See, also, Heron v. Railway Co., 68 Minn. 542, 71 N. W. 706. The damages sustained by the Denver Company were, therefore, not only the loss of its own property destroyed or injured, but included also the amounts it had to pay for the immediate care of its injured passengers, and of the remains of such as were killed, and the amounts it was required to pay its passengers, and owners of property on its passenger train, in satisfaction. for their injuries and losses from the collision. This disposes of all assignments of error which question the right of the intervener to have any relief.

On reviewing the action of the circuit court as to the specific items of damage allowed to the intervener, it should be borne in mind that the court was not simply engaged in the adjudication of issues between ordinary litigants. In this foreclosure suit it had taken possession of the railroad property, and was operating the railroad by its receiver, and was thus exercising. administrative functions, temporarily," in connection with and in aid of the foreclosure suit. The damages claimed in this intervention against the receiver because of the torts of his employés in the movement of one of his trains would, if allowed, be classed as operating expenses *243of the railroad under the receiver. 20 Am. & Eng. Euc. Law, 385. The court, in considering these claims, was supervising the action of its own receiver in the administration of the business of the railroad, and, for the purpose of directing his action, could properly ascertain his liabilities according to the business methods customarily adopted by careful and prudent railroad corporations under like circumstances, avoiding needless delays and vexatious and expensive litigation, where the right .of the matter was obvious to the court, and where it could see that no real dispute as to facts existed. The fact that before the hearing a sale of the railroad property had been made upon the condition referred to did not change the nature of the proceeding further than to make it necessary that the New Midland Company, because of its assumption of ultimate responsibility, be made a party to the intervention, with the right to present any objections or defenses against the claims which the receiver might have urged. The intervention was still a proceeding in the matter of the receivership in the foreclosure suit, as much as if the railroad, at the time of the hearing, was still in the hands of the receiver; and the court, if clearly satisfied that the receiver was liable, and that the showing fixed the amount of a claim beyond doubt or serious contention, would properly allow it, without the delay and expense of formal litigation. If a claim were for unliquidated damages, — as for personal injuries from a moving train of the receiver, the amount being in dispute, as well as allegations of negligence and of contributory negligence, — If would, from its nature, have to be determined by a jury in an action at lav/, as was done in Thompson v. Railway Co., 35 C. C. A. 357, 93 Fed. 384, although any judgment obtained by the claimant could only be satisfied in the intervention in the foreclosure suit. The same course would have to be taken, as to the trial of such a claim, if the receivership were still active. But it would have been an abuse of the power of the court in this case, where the right of recovery was clear, had it required or permitted extended and expensive litigation as to claims, the amounts of which were readily ascertainable upon the showings at the hearing, satisfactory to the court, and unquestioned as to accuracy.

The errors assigned upon the allowance of particular items are generally but repetitions or amplifications of the general objections going to the right of the intervener to recover any damages. As to the claim for damages to rolling stock, §27,77.1.31, it was, on the hearing before the special master, agreed and admitted that petitioner’s Exhibit No. 7, which specified such damages aggregating that sum, was a true statement of the damages to rolling stock of the intervener as the result of the collision, explosion, and fire, and that the intervener was responsible to the Pullman Company and the Rio Grande Western Company for their coaches named in that statement. This admission left no issue as to the amount of that claim. And the same is true in respect to the item of §205.43, paid by the intervener to the United States on account of registered mail matter and equipment destroyed by the collision and fire, it having been admitted at the same hearing that the amount was rea*244sonable, and the proof of payment by the intervener sufficient. As to the claim for $1,240.75 paid by the intervener to its passengers, named in its petition, in settlement of their respective claims for personal injuries and loss of baggage, the receiver, in his answer, admits that at the time of the making of such settlement he conceded that the amounts were reasonable for the passengers to receive on account of such losses and injuries. And so in respect to the other items making up the aggregate of $31,863 allowed by the special master, and also by the court, it is enough to say, without going further into details, that the evidence sufficiently showed that they consisted of settlements for damages to property carried on intervener’s train, and in payments of expenditures made necessary by and resulting from the collision; all of which were actually and properly paid by the intervener. Neither the fact of payment by the intervener nor the reasonableness of the amount was questioned. The general holding that the receiver was liable to the intervener disposed of all contention as to these items. The item of $999.11, for moneys to that amount paid by the intervener to owners of express matter carried on intervener’s passenger train, and destroyed in the collision and fire, was properly allowed by the court. It was not questioned that the intervener had paid that amount, upon proofs which, though ex parte, were such as are customarily accepted as satisfactory by railroad companies in cases of such losses. No suspicion as to the accuracy and correctness of such proofs was suggested. The liability of the receiver being clear, and the losses and their amounts appearing by customary proofs, not contested or questioned as to accuracy, on which the payments by the intervener had been made, there was no real issue in respect to the item to require or justify any litigation, delay, or expense. In supervising the administration of the receiver in respect to this item, the court rightfully recognized and acted upon the methods in use in the common course of carrying on the business of such railroads, and the proofs, which might and should have been accepted as satisfactory by the receiver, on which to recommend to the court the allowance of the item, had he still continued in the active operation of the railroad. Upon the hearing in this intervention it was as much within the discretion of the court to accept such uncontroverted customary proofs, when satisfied of the correctness of the same, and thus avoid needless expense and delay, as if the railroad were then still under the management of its receiver.

The allowance of interest from July 14, 1898, the day when the decision of the court was filed on which the decree was afterwards entered, was made by the judges who rendered the decision and also signed the decree, and was within the discretion of the court. Frazer v. Carpet Co., 141 Mass. 126, 4 N. E. 620.

The provision in the decree requiring the Colorado’ Midland. Railway Company, upon notice from the intervener of any claim made against it on account of said collision, wreck, explosion, or conflagration, to compromise and settle such claim or defend against the same, paying any judgment rendered thereon against the interven*245er, with interest, costs, and reasonable counsel fees, is a proper provision for the satisfaction of the liabilities of the receiver in conformity with the condition of the foreclosure sale above referred to.

The decree of the circuit court is affirmed, with costs.
