The Mayor and Aldermen of Birmingham granted to the Elyton Land .Company, a corporation, the franchise and right to construct a double street car track along the center of First avenue from Nineteenth street to Twenty-second street, under, the covenant and agreement of the Elyton Land Company “that ip. case any other street railroad company should desire the use of the former’s track on First avenue between Nineteenth street and Twenty-second street, such user shall be granted, .upon-the payment of a just, fair and usual compensation, such as is generally paid under like circumstances in other cities, such user to be enjoyed with the usual restrictions and limitations.” The agree*514ment between the Elyton Land Company and the Mayor and Aldermen,.among others, contained the following covenant: “And said Elyton Land Company further agrees to furnish said street car line with first-class street cars and equipment, and to have cars runping upon the same within six months from the date hereof. Said cars are to be drawn by horses, mules or steam locomotives, as said Elyton Land Company may prefer, and if an engine be used the same must be enclosed to resémble street cars, with glass sash” etc. This agreement bears date April-24th, 1885. The bill avers a compliance in all respects by the Elyton Land Company with the terms and covenants entered into with the Mayor and Aider-men of the city of Birmingham, and that complainant, the Highland Avenue & Belt Railroad Company, succeeded to all the rights and privileges of the Elyton Land Company. The bill then avers that respondents are running locomotives and engines over and along its double tracks between Nineteenth and Twenty-second streets without paying or offering to pay, and refuses to pay, a reasonable and just compensation for such, user of its tracks. - The complainant avers that it is willing for such use, upon payment of what is fair and reasonable. The prayer of the bill is for a temporary injunction and reference to the register to ascertain and report what would be a fair and just compensation for the use of the tracks, and for an order requiring its payment or satisfactory security for its payment.
For answer to complainant's bill, the respondents state that they have always been ready and willing to pay complainant what is justly due for the use of complainant’s tracks, but aver that ■ complainant has demanded and continues to demand a much greater amount than is justly due. The defense of respondents is founded upon a contract and agreement made and entered into between the Elyton Land Company1, complainant grantor, and the Birmingham Street Railway Company on the 18th of July, 1885, prior to the succession of complainant to the rights of the Elyton Land Company. That agreement is made exhibit A to the answer, and is as follows: “Whereas there are now suits and differences pending by and between parties hereto, as to the right of the Elyton Land Company to construct and operate a Street R. R.-on and over First *515avenue as fully described hereafter, now for a full and complete settlement of the differences existing in said matter, it is agreed as follows :
“1st. That the Elyton Land Co. will at once, or as soon as practicable, construct a double track of Street R. R. of the gauge as now used by the party of the second part upon and over the following : Beginning at Nineteenth street and First avenue, North, to run East along the center of First avenue, to Twenty-second street; thence South across a bridge, to be. constructed by the party of the first part, to Avenue ‘E’ South, the said track to be double track of thirty pound rails.
“2d. • It is further agreed and understood that the said double track shall be for the joint use of both parties for the running of their cars on same ; that the cars of each are to be run and operated as not to interfere with the schedule of each other ; the party of the first part or assigns are to bear all expenses in keeping the tracks in good repair and condition; the party of the second part or its assigns are to pay the party of the first part for the use of said track as follows : Ten (10) per cent on one-half of the original cost of that part or portion of said track including the bridge, used by the party of the second part or its assigns ; payments to begin from the time said party of the second part or assigns shall begin to use said track or tracks, and to cease when the said party of the second part shall cease to use the same ; payments to be made monthly. It is agreed and understood that if the management of said party of the second part shall at any time deem it necessary to discontinue for a time the use of said track or any portion of the same, then the payments shall cease till the use is resumed, which right to be resumed is hereby understood to exist.
' “It is further agreed and understood that the Birmingham Street Railway Company or assigns shall at all times have the right to connect any part of its line or track with the track or tracks constructed by said Elyton Land Co. as aforesaid.
“It is further agreed and understood that the said Elyton Land Company shall have the right to connect the said tracks at First avenue and Nineteenth street with the present track of the Birmingham Street Railway Co., for the purpose and only for the purpose of the *516said two companies, turning or reversing cars or engines ; provided, however, the said connection shall be made at the cost of said Land Co., and provided further that the turning or reversing of the cars of said Land .Co. at said point, shall not interfere with the cars of the Birmingham Street Railway Co.; that is to say the Birmingham Street Railway Co. shall have an unobstructed passage for its cars running along its present line.
‘ ‘It is further agreed and understood that the above is a full settlement of the differences now existing between the parties hereto, and it is agreed and understood that all suits, appeals .and proceedings now pending are to be dismissed, and all claims for damages growing out of the same shall be, and the same are, hereby discharged, and each party pays its own costs.
“Provided, however, that this agreement shall not bé construed as affecting the rights of either party in any future question or litigation, but is meant and intended as a settlement of matters now pending.”
The respondents aver that they have succeeded to the rights of the Birmingham Street Railway Company, and that they are indebted only as stipulated in this agreement. The answer is made a cross-bill; a reference is asked for, that the amount due under the agreement may' be ascertained; and respondents aver a readiness to pay the same.
By the answer to respondents’ cross-bill it is averred, that when the agreement of July 18th, 1885, was entered into between the Elyton Land Company and the Birmingham Street Railway Company, both corporations were using only street cars drawn by horses; 'that for such street cars, rails of thirty pounds were ample ; that the cost' of construction of the track of thirty pound rails was about $2,176, and that on account of increased travel and public demand it became necessary to substitute steam and electricity for the horse car, and complainants reconstructed their track and substituted rails weighing 50 or 56 pounds, at a cost of nine thousand dollars ; that the reconstruction was necessary, and the expenditure reasonable. It is shown and respondents admit that they have abandoned the horse cars and are using steam engines and electricity for drawing their cars upon complainant’s track, but claim that under the agreement of July 18th, they can not be required to pay *517more than the original cost of- laying the track with thirty pound rails.
Though there is much pleading and a great deal of evidence, this is the real issue of merit between the litigants. We think it clear that if the respondents had continued the use of horse cars, and the Elyton Land Co. had constructed the more expensive- tracks for its own interests, it would not be. justified in charging a greater rate than that provided in the agreement. Suppose the Elyton Land Company or complainant, had found street cars drawn by horses ample for its business and had continued the use of such cars'without a change of the track, and respondents had substituted engines to draw their cars over and upon the track constructed of thirty pound rails, could they compel the complainant to keep in repair the track for their use according to the agreement, and receive only the compensation provided by the agreement?
The evidence shows quite satisfactorily that the cost of keeping in good repair a track of thirty pound rails, for the use of dummy engines and locomotives along First avenue with the avenues and streets paved as they are, would be well nigh ruinous. We recognize the principle to its fullest extent, that courts can not make contracts for parties, and we have not overlooked the provision in the agreement which provides that “The Elyton Land Company shall have the right to connect the said tracks at First avenue and Nineteenth street with the present track of the Birmingham Street Railway Company for the purpose and only for the purpose of the said two companies turning or reversing cars or engines; provided, however, the said connection shall be made at the "cost of the said Land Company, and provided further that the turning or reversing of the cars of the said Land Company at said point, shall not interfere with the cars of the Birmingham Street Railway Company; that is to say, the Birmingham Street Railway Company shall have an unmolested passage for its cars running along its present line.” We do not interpret this provision to- confer any right or privilege upon the respondents, but it was inserted wholly for the benefit of the Elyton Land Company. At that time the Birmingham Street Railway Company owned and was operating a horse car line from First avenue along Nine*518teenth street to Second avenue. The insertion of the provision authorized The Elyton Land Company to connect with this line, only for the purpose of turning its cars or engines, and even this privilege had to be used in such a manner as not to ' interfere with the • unobstructed passage of the cars of the Birmingham Street Railway Company. This was the purpose'and meaning of the provision, and it has no reference to the rights of the respondents acquired under the contract to use the tracks of the Elyton Land Company.
While it is not permissible to vary, add to or alter a written contract, by parol, it is legitimate and often necessary to consider the situation of the parties and existing circumstances in order to get at the intention of the parties and the true meaning of a contract. The rule is well stated in Pollard v. Maddox, 28 Ala. 320, in the following language : “Contracts must be interpreted in the light of surrounding' circumstances. The occasion which gives rise to them, the relative position .of the parties, and their obvious design as to the objects to be accomplished must be looked at, in order to arrive at their true meaning, and to enable the court to carry out their intention, if lawful.” The same principle is recognized in Tenn. & Coosa R. R. Co. v. East Ala. Railway Co., 73 Ala. 426 ; Williams v. Glover, 66 Ala. 189.
Applying these rules of interpretation, our conclusion is, that when the agreement of July, 1885, was made, the parties had in view a continuation of such use of the tracks as was then in operation, and for which rails of thirty pounds weight were suitable, and that there was no concurrence of mind as to the contingency, that if the interest of both parties subsequently required the substitution of engines for mere horse power, which would ■necessitate more than a quadrupling of expense in constructing and keeping in repair the tracks, the compensation, notwithstanding, should remain the same. This view neither adds to nor varies the written agreement; and accords with equity and good conscience.
The mayor and board of aldermen of Birmingham granted to the Elyton Land Company the right to construct its double track upon consideration that the latter “agreed that if any other street railroad company should desire the use of the former’s tracks on First avenue between Nineteenth and Twenty-second street, such user *519■shall be granted, upon the payment of a just, fair and usual compensation,” etc. We find nothing in the facts of the ease to exclude the respondents from the benefit of this provision, and complainant’s bill seems to concede the right upon the payment of such compensation.
In their brief appellees do not question the equity of complainant’s bill, the whole controversy on their part being rested upon a right growing out of the contract between the Elyton Land Company and the Birmingham Street Railway Company.—Thornton v. S. & B. R. R. Co., 84 Ala. 109; Cooper v. A. & A. R. R. Co., 85 Ala. 106 ; S. & N. A. R. R. Co. v. H. A. & B. R. R. Co., 98 Ala. 400 ; 1 High on Inj., § 608.
We are of opinion the court has no power to fix the rate-of compensation to be paid in the future. That must be determined by the agreement of the parties. ■It may, however, ascertain and decree payment for past uses, and enforce payment, if it becomes necessary to do so, by its restraining power, a power which under the facts of the case should not be exercised unless it becomes necessary in order to enforce its own decree.
The decree of the chancery court is reversed and annulled, and it is ordered and decreed, that complainant is entitled to relief. The register will hold a reference according to the rules of the court, and ascertain and report what compensation should be paid to complainant, according to the principles of law declared in the opinion.
It is decreed that cross-complainants are not entitled ■to relief under their cross-bill, and as a cross-bill for affirmative relief the same is dismissed out of court.
Reversed, rendered and remanded.
