Prior to and during the year 1880 a' railroad company, known as the Chicago & Grand Trunk Railway Company, owned and operated a line of railroad now owned and operated by the appellant. Its line of road ran east and west through the station called Maynard, in Lake county, in this State. In the year 1880 a railroad company, known as the Chicago & Indianapolis Air-Line Railway Company, constructed the line of road now owned and operated by appellee Chicago, Indianapolis & Louisville Railway Company, known as the “Monon,” which line of road crossed the line of the Grand Trunk Western Railway at the station of Maynard. The appellant is the successor in rights and interests of the Chicago & Grand Trunk Railway Company, and the appellee Chicago, Indianapolis & Louisville Railway Company is the successor in rights and interests of the Chicago & Indianapolis Air-Line Railway Company. At the time the last-mentioned line of railway was constructed the two companies then interested, the Chicago & Grand Trunk Railway Company and the Chicago & Indianapolis Air-Line Railway Company, entered into a written contract, as follows :
‘ ‘ This agreement made and entered into near July 16, 188 — , by and between the Chicago & Grand Trunk Railway Company, party of the first part, and the Chicago & Indianapolis Air-Line Railway Company, party of the second part, witnesseth: That the party of the first part, for and in consideration of the performance by the party of the second part of the stipulations and agreements hereinafter set forth, doth give and grant to said party of the second part the right to construct and operate said Chicago & Indianapolis Air-Line Railway over and across the right of way of said Chicago & Grand Trunk Railway at the point where said Chicago & Indianapolis Air-Line Railway, as now located and in process of construction, shall cross the same at or near Maynard station on the line of said Chicago & Grand Trunk Railway, which said railway of the party of the second part shall have constructed, kept, and maintained at a grade on a level with the railway of said party of the first part at the point of crossing as above" specified herein.
*171And said party of the second part, in consideration of the right to construct and operate said Chicago & Indianapolis Air-Line Railway across the right of way of said party of the first part, as above granted and set forth, agrees to construct, put in, and maintain good and sufficient frogs and crossings at the points where the track of said Chicago & Indianapolis Air-Line Railway crosses the track of the Chicago & Grand Trunk Railway, as aforesaid, and should the party of the first part, at any time hereafter, construct and lay down additional track or tracks at said point of intersection the party of the second part agrees in like manner to construct, put in, and maintain sufficient frogs and crossings to enable the party of the first part to cross the track or tracks of said second party’s railway.
All of which crossings shall be put in at and upon the grade of the railway of .the party of the first part, and shall be done in a good and substantial manner, so that the party of the first part shall be able to operate its road at that point with convenience and safety, and that said crossings shall be so maintained and kept in repair by the party of the second part at its individual expense forever.
'And the party of the second part further agrees that it will at said point of intersection, erect, put up, and forever maintain good and substantial semaphores, or other signals, and provide the requisite watchmen to take charge of and operate the same, all of which shall be at the individual expense of said party of the second part.
In witness whereof the parties have hereunto set their hands the day and year first above written.”
Under this agreement the Chicago & Indianapolis Air-Line Railway Company and its successor, the Monon Company, have, ever since said crossing was completed, maintained a semaphore, signal and watchmen at said crossing at their own expense.
On May 4, 1905, appellee Monon Company filed with the railroad commission of this state a written petition praying that an interlocking system be established at this crossing, and also at its crossing with another road in the close vicinity. Due notice was given to all the parties. The railroad commission met pursuant to statute, examined the crossing, *172and afterwards, all the railroad companies interested appearing, the commission ordered that interlocking switches should be installed and put in use at this crossing, and that the cost of installing the interlocking plant should be apportioned between appellant and appellee Monon Company, upon the basis of functions of levers used in the operation of the plant for the benefit of the several roads respectively. It further ordered that the expense of operating the device should be sustained by the two companies interested and affected, upon the same basis, except that the petitioner should contribute the sum of $780 per annum to the expense fund, and the expense in excess of this sum should be apportioned between the two companies as above stated. Afterwards the appellant herein filed its petition in the Lake Circuit Court, setting forth a description of the interlocking system ordered installed by the railroad commission, and the manner of operating the same, averring that the cost of installing such plant would be $5,000; that the cost of maintenance and operation would be $1,600 per annum, and that the present expense of said crossing was $900; and objecting to the order and regulation of the railroad commission made relative to said crossing, on the ground that it compels the Grand Trunk Western Railway Company to pay part of the cost and expense of erecting said interlocking system, including semaphores and other signals, and for the reason that it makes no provision for the payment by the Monon Company of any increased cost of maintaining and operating the signals. It further alleges that, by virtue of the contract above specified, it became the duty of the Monon Company to pay all the cost and expenses of keeping in repair, operating and managing the crossing aforesaid; that the order is in dereliction of the rights of the appellant under the contract, and asks an order to annul and set aside the order, or to modify the same, so far as to compel the Monon Company to pay all the cost and expense of installing, operating and maintaining the interlocking switch at the crossing.
*1731. The proceeding instituted by the Monon Company to have an interlocking switching device maintained at this crossing is pursuant to the statute upon that subject, which originally lodged the power to order the installation of such interlocking switching device in the hands of the Auditor of State, from whose hands it was transferred by the railroad commission act to the hands of the railroad commission.
2. The first question that confronts the court in the consideration of this case is the question of jurisdiction. It is contended by appellee Monon Company that the action of the railroad commission on this subject is final and conclusive on the parties, and not subject to review in court. The argument is made that the law providing for the installation of interlocking switching devices at railroad crossings is an exercise of the police power of the State; that it is a legislative act delegated to the railroad commission, and upon which the parties named have no right to a judicial hearing, unless such right is expressly conferred by law, and that no such hearing is provided for in the statute. Were said appellee’s premises well grounded, its argument would appeal to the court with a great deal of cogency, but is the premise sound? Section two of the act of 1897, approved March 8 (Acts 1897, p. 237, §5158c Burns 1901), provides for the protection of railroad crossings by interlocking switches, and vests the authority to hear and determine all matters connected with the establishment of such, in the Auditor of State. Section three of the railroad commission act (Acts 1905, p. 83, §5405c Burns 1905) confers authority on the commission to adopt all necessary regulations to govern car service and the transferring and switching of cars from one railroad to another at junction points, to require and supervise the location and construction of sidings and connections between railroads, to supervise the crossing of tracks and side-tracks of railroads by other railroads now in process of *174construction or extension, or which may hereafter be constructed or extended, and vests in the commission the authority theretofore vested in the Auditor of State under the laws of the State with reference to the crossing of railroads by other railroads or by railroads operated by electricity, the installation and maintenance of interlocking appliances at such crossings, and the supervision and regulation of private car line service.
Section six of said act (§5405f Burns 1905) provides, among other things: “If any such railroad company, or other corporation or party in interest shall be dissatisfied with any order or regulation of said commission respecting the location or construction of sidings, switches or connections between railroads, or the crossing of one railroad by another, * * # such dissatisfied company or party may, within thirty days after any such order or regulation has been made, file a written petition to the circuit or superior court of the county wherein any such siding, switch, connection, crossing, junction point or private' track is situate, setting forth therein the particular cause or causes of objection to the order or regulation of the' commission, complained of. * * * After the filing of such petition, and upon proof of the service of the said notice, or upon the appearance of said commission to such petition, the said proceedings shall be set down for hearing without delay, and shall be heard and determined as a suit in equity, without a jury. Any such court shall have power to affirm the action of said commission so complained of or to change, modify, or set aside the same, as justice may require.” An opportunity is thus given to those whose rights are affected by the order of the railroad commission in these respects to have the question of their rights heard and determined in a judicial tribunal. This statute should receive a liberal construction in favor of the right of the citizen to have his cause thus heard and determined in court, and we are constrained to hold that the term “any order or regulation * * * re*175specting # * * the crossing of one railroad by another” is broad enough to include orders made by the railroad commission .installing interlocking plants for the purpose of protecting such crossings.
3. Recognizing appellant’s right to a judicial hearing of its cause, the burden rests upon it to show affirmatively, by the averment of facts set forth in its petition, that the order of the railroad commission with reference to the installation of the interlocking switch at the crossing of the two roads mentioned and described in the petition does it an injustice, or is in some manner unwarranted by law.
4. The ease does not come before this court on appeal. It is here as an attack upon the fairness or validity of the order of the railroad commission, the presumption being that the order is valid, fair, and just to all the parties. The ground of appellant’s complaint against the order of the railroad commission.in installing the interlocking switch at the crossing is that the order, so far as it apportions the cost and expense of installing the device and maintaining and operating the same, invades the contractual rights of the appellant as against the appellee Monon Company; that the contract entered into between the predecessors in right, the Chicago & Grand Trunk Western Railway and the Chicago & Indianapolis Air-Line Railway, places the entire burden of protecting the crossing upon the appellee Monon Company, and that the order of the railroad commission, requiring appellant to pay any part of this expense, is in violation of the appellant’s constitutional right under its contract. This contention is met by the appellee Monon Company: (1) By the proposition that the installation of the interlocking switch by the railroad commission is the exercise by it of the police power of the State, delegated to the commission by the legislature; that the railroad commission, in the exercise of this power, is bound by no private contract between the parties; that the constitu*176tional provisions of the state and federal government, protecting the contractual rights of parties, does not apply to prevent the exercise of the police power of the State; that such contracts cannot be set up against the exercise of such power by the legislature or the authorities to whom the legislature has delegated the power; and that the railroad commission, therefore, in the exercise of this power, is in no way bound to recognize the contract between the two railroad companies respecting the expenses of protecting the crossing. (2) That the contract itself will not bear any such construction as is contended for by appellant; that the terms of the contract preclude the idea that it was in the minds of the contracting parties that such an expense as is involved in the erection, maintenance, and operation of the interlocking switch was intended to be imposed upon or assumed by the Monon Company or its predecessor.
5. First, of appellee Monon Company’s contention that the railroad commission was not bound to recognize said appellee’s rights under the contract set up in the petition between the predecessor of the Monon Company and the predecessor of the Grand Trunk Western Railway Company at the time the crossing of the two roads was made —it is undoubtedly the law that private contracts between corporations or natural persons can in no way preclude the legislature from enacting and enforcing laws for the protection of the lives, persons, and morals of the citizens of the State. The right to enact such laws is the right of self-defense that inheres in the State as it does in the individual, and there is no question but that the law regulating the location, erection, and maintenance of interlocking switches at railroad crossings belongs to this class of legislation. But when this is conceded it does not necessarily follow that the contractual rights of the appellant are obliterated.
6. The law itself in nowise interferes with them. It is in the execution of the law, not in its letter or its spirit, that it is contended the appellant’s contractual rights *177are invaded. The law regulating this subject places its enforcement in the hands of the railroad commission, and, it is true, vests the commission with power and authority to apportion the expenses of the work between the roads interested; but it lays down no rule for their guidance that in anywise trenches on the contractual rights of either road as against the other. It leaves the commission to be guided in the work of apportioning the expense by the general rules of law and justice. It leaves it perfectly free to carry out and enforce the duties and obligations of the roads as between themselves, precisely as a court of justice might enforce these duties and obligations, and we hold that in the performance of this duty the railroad commission is bound by the same rules of law that would govern a court in deciding the same question. The question presented for the commission do determine, as it would be to a court, is what is just and right between the two companies who must bear this expense, and if there is a contract existing between the companies, by the terms of which one of them is in duty bound to bear all the expense, the railroad commission may not properly ignore such contract, and to do so would be good ground for petition to the circuit court for redress.
7. That it is a police power of the State which the commission executes makes no difference. Where the execution of this power is entirely consistent with the protection of the rights of the citizen under his contract, it must be protected. If it is not so consistent, then the contract must give way to public necessity. 'But in this case there can be no pretense that the exercise of the police power invoked would be in the least interfered with by the full recognition of appellant’s rights under the contract set up in the petition. It could make no possible difference to the public safety whether all of the expense of the installation, maintenance, and operation of the interlocking switching plant to be installed was borne entirely by one of the railroad com-*178parties interested, or whether the expense was to be divided between the two. So we hold that, whatever rights the appellant had in the contract set np, it was the duty of the railroad commission to recognize them, and if they have been violated in the order the appellant has a right to redress in the court.
8. Does the contract set forth in appellant’s petition impose upon the appellee Monon Company the burden of paying the expense of installing, maintaining and operating the interlocking switch in question? The stipulations of the contract bearing upon the question are as follows:
“And said party of the second part, in consideration of the right to construct and operate said Chicago & Indianapolis Air-Line Railway across the right of way of said party of the first part, as above granted and set forth, agrees to construct, put in, and maintain good and sufficient frogs and crossings at the point where the track of the Chicago & Indianapolis Air-Line Railway crosses the track of the Chicago & Grand Trunk Railway, as aforesaid, and should the party of the first part, at any time hereafter, construct and lay down additional track or tracks at said point of intersection the party of the second part agrees in like manner to construct, put in, and maintain sufficient frogs and crossings to enable the party of the first part to cross the track or tracks of said second party’s railroad. All of which crossings shall be put in at and upon the grade of the railway of the party of the first part, and shall be done in a good and substantial manner, so that the party of the first part shall be able to operate its road at that point with convenience and safety, and that said crossings shall be so maintained and kept in repair by the party of the second part at its individual expense forever.”
The first and second clauses of this contract clearly relate simply to the laying of the crossing, not, in any manner, to its protection by signals or guards, and the order of the railroad commission in no way could affect the rights of the parties under this claim of their contract.
*1799. *178The establishment of the interlocker was to guard the *179crossing, not in any way to affect its repair or its maintenance. The expression.in the second clause, “shall be done in a good and substantial manner, so that the party of the first part shall be able to operate its road at that point with convenience and safety,” relates to the manner in which the crossing shall be put in, and not to the manner of its being guarded.
10. The only part of the contract that has reference to the guarding of the crossing is that section providing for the erection and the maintenance, at the point of intersection, of good and substantial semaphore signals. It would be interpolating into this contract terms which were clearly not in the minds of the parties at the time it was made to hold that it would include interlocking switches and signals erected at far distant points from the intersection, as are contemplated by the interlocking system, and clearly do not apply to the character of work that is proposed by the interlocking device.,
11. The order of the railroad commission in directing the installation of the interlocker at this point recognizes the rights of the appellant under its contract, and in the very carefully-considered order prepared by the commission they have required the Monon Company to pay first into the fund, to be used for the operation of this plant, the sum of $780 before there shall be an apportionment of costs, and it is not made manifest by the petition that this is not a fair and just, apportionment of the expenses connected with the installation, maintenance, and operation of this plant, having in view the rights of the appellant under its contract. If the contract could be construed so as to require the payment of all the expenses of the plant by appellee Monon Company, then the order of the railroad commission would clearly be an invasion of the rights of the appellant; but the contract relied upon admits of no such construction.
The judgment of the court below is affirmed.
