the scope of the contract as construed according to the usual
meaning of the words used.
A contract between two railroads for maintaining the physical
cost of a crossing and guarding it by good and substantial
semiphores or other signals is not impaired by a subsequent act
requiring an interlocking system and apportioning the expense in a
different manner than provided in the contract. The contract did
not embrace such a system.
The facts, which involve the constitutionality of an order of
the Railroad Commission of Indiana directing installation and use
of interlocking plant at a railroad crossing and apportioning the
expense of executing the order, are stated in the opinion.

MR. JUSTICE VAN DEVANTER delivered the opinion of the Court.
This is a suit to secure the annulment or modification of an
order of the Railroad Commission of Indiana directing the
installation and use of an interlocking plant at the crossing of
two railroads in that state, and apportioning between them the
expense of executing the order. The suit proceeds upon the theory
that a contract between the owners of the roads, entered into
before the enactment of the statute upon which the order rests,
imposes upon the junior road all the expense of maintaining and
guarding the crossing in whatever manner may be essential to make
its use safe and convenient, and that the order, by imposing a part
of the expense of its execution upon
Page 221 U. S. 403
the other road, impairs the obligation of the contract, and
therefore is void.
The appellate court of the state, having regard to the terms of
the contract and to the conditions existing when it was made,
twenty-five years before, held that it did not provide for or
contemplate any such elaborate system of protecting and guarding
the crossing as is involved in the use of an interlocking plant,
and therefore that the expense entailed by the order was not within
the purview of the contract. And that court, after observing that
the statute invested the Commission with the authority to make a
just, but not an arbitrary, apportionment of the expense, and that
the apportionment as made did not appear to be unjust or arbitrary,
sustained the order. 40 Ind.App. 168.
Observing first that the order is a legislative act by an
instrumentality of the state exercising delegated authority
(
Prentis v. Atlantic Coast Line Co., 211 U.
S. 210,
211 U. S.
226), is of the same force as if made by the
legislature, and so is a law of the state within the meaning of the
contract clause of the Constitution (
New Orleans Water Works
Co. v. Louisiana Sugar Refining Co., 125 U. S.
18;
St. Paul Gas Light Co. v. St. Paul,
181 U. S. 142,
181 U. S. 148;
Northern Pacific Ry. Co. v. Minnesota, 208 U.
S. 583,
208 U. S.
590), we come to consider whether it does impair the
obligation of the contract. Obviously it does not if the contract
creates no obligation respecting the expense which the order
entails.
The contract is set forth at length in the state court's
opinion, and need not be reproduced here. It declares explicitly
that the duty of constructing and properly maintaining the physical
crossing of the two roads, and bearing the expense incident
thereto, shall rest with the junior road, but its only provision
respecting what shall be done in the way of guarding the crossing
is that "good and substantial semaphores or other signals, and . .
. the requisite watchmen to take charge of and operate the same,"
shall be provided and maintained by that road at
Page 221 U. S. 404
its "individual expense." There is no reference to an
interlocking plant, nor any general language that would include
one. The words "semaphores or other signals" do not do so. An
interlocking plant is so much more than a signaling device that it
is quite beyond their usual meaning. That meaning has been applied
to them during twenty-five years of practice under the contract,
and another ought not to be substituted now.
We conclude, as did the state court, that the contract does not
embrace the expense which the order entails, and therefore that the
order does not, by apportioning that expense, impair the obligation
of the contract.
But, to avoid any misapprehension that otherwise might arise, we
deem it well to observe that we do not, by what is here said,
suggest or imply that the contract, if its terms were broad enough
to include the expense in question, would be an obstacle to the
apportionment of that expense under the state statute.
