The Safety Appliance Act of March 2, 1893, 27 Stat. 531, c. 196,
as amended March 2, 1903, 32 Stat. 943, c. 976, embraces all
locomotives, cars, and similar vehicles used on any railway that is
a highway of interstate commerce, and is not confined exclusively
to vehicles engaged in such commerce.
The power of Congress under the commerce clause of the
Constitution is plenary and competent to protect persons and
property moving in interstate commerce from all danger, no matter
what the source may be; to that end, Congress may require all
vehicles moving on highways of interstate commerce to be so
equipped as to avoid danger to persons and property moving in
interstate commerce.
As between opposing views in regard to the construction of a
statute, the Court in this case accepts the one in accord with the
manifest purpose of Congress.
It is of common knowledge that interstate and intrastate
commerce are commingled in transportation over highways of
interstate commerce, that trains and cars on the same railroad,
whether engaged
Page 222 U. S. 21
in one form of traffic or the other, are interdependent, and
that absence of safety appliances from any part of a train is a
menace not only to that train but to others.
164 F. 347 affirmed.
The facts, which involve the construction and constitutionality
of certain sections of the Safety Appliance Acts, are stated in the
opinion.

MR. JUSTICE VAN DEVANTER delivered the opinion of the Court.
This was a civil action to recover penalties for the violation
in specified instances of the Safety Appliance Acts of Congress. 27
Stat. 531, c. 196, 32 Stat. 943, c. 976. The government prevailed
in the district court, and the defendant sued out this direct writ
of error.
Briefly stated, the case is this: the defendant, while operating
a railroad which was "a part of a through highway" over which
traffic was continually being moved from one state to another,
hauled over a part of its railroad, during the month of February,
1907, five cars the couplers upon which were defective and
inoperative. Two of the cars were used at the time in moving
interstate traffic and the other three in moving intrastate
traffic, but it
Page 222 U. S. 24
does not appear that the use of the three was in connection with
any car or cars used in interstate commerce. The defendant
particularly objected to the assessment of any penalty for the
hauling of the three cars, and insisted first that such a hauling
in intrastate commerce although upon a railroad over which traffic
was continually being moved from one state to another was not
within the prohibition of the safety appliance acts of Congress,
and second that if it was, those acts should be pronounced invalid
as being in excess of the power of Congress under the commerce
clause of the Constitution. But the objection was overruled, 164 F.
347, and error is assigned upon that ruling.
The original Act of March 2, 1893, 27 Stat. 531, c. 196, imposed
upon every common carrier "engaged in interstate commerce by
railroad" the duty of equipping all trains, locomotives, and cars
used on its line of railroad in moving interstate traffic with
designated appliances calculated to promote the safety of that
traffic and of the employees engaged in its movement, and the
second section of that act made it unlawful for "any such common
carrier" to haul or permit to be hauled or used on its line of
railroad any car "used in moving interstate traffic" not equipped
with automatic couplers capable of being coupled and uncoupled
without the necessity of a man's going between the ends of the
cars. The Act of March 2, 1903, 32 Stat. 943, c. 976, amended the
earlier one and enlarged its scope by declaring,
inter
alia, that its provisions and requirements should
"apply to all trains, locomotives, tenders, cars, and similar
vehicles used on any railroad engaged in interstate commerce, and
in the territories and the District of Columbia, and to all other
locomotives, tenders, cars, and similar vehicles used in connection
therewith."
Both acts contained some minor exceptions, but they have no
bearing here.
The real controversy is over the true significance of
Page 222 U. S. 25
the words "on any railroad engaged" in the first clause of the
amendatory provision. But for them, the true test of the
application of that clause to a locomotive, car, or similar vehicle
would be, as it was under the original act, the use of the vehicle
in moving interstate traffic. On the other hand, when they are
given their natural signification, as presumptively they should be,
the scope of the clause is such that the true test of its
application is the use of the vehicle on a railroad which is a
highway of interstate commerce, and not its use in moving
interstate traffic. And so certain is this that we think there
would be no contention to the contrary were it not for the presence
in the amendatory provision of the third clause -- "and to all
other locomotives, tenders, cars, and similar vehicles used in
connection therewith." In this there is a suggestion that what
precedes does not cover the entire field; but at most it is only a
suggestion, and gives no warrant for disregarding the plain words,
"on any railroad engaged" in the first clause. True, if they were
rejected, the two clauses, in the instance of a train composed of
many cars, some moving interstate traffic and others moving
intrastate traffic, would, by their concurrent operation, bring the
entire train within the statute. But it is not necessary to reject
them to accomplish this result, for the first clause, with those
words in it, does even more -- that is to say, it embraces every
train on a railroad which is a highway of interstate commerce,
without regard to the class of traffic which the cars are moving.
The two clauses are in no wise antagonistic, but, at most, only
redundant, and we perceive no reason for believing that Congress
intended that less than full effect should be given to the more
comprehensive one, but, on the contrary, good reason for believing
otherwise. As between the two opposing views, one rejecting the
words "on any railroad engaged" in the first clause and the other
treating the third clause as redundant, the latter is to be
preferred, first because it is
Page 222 U. S. 26
in accord with the manifest purpose, shown throughout the
amendatory act, to enlarge the scope of the earlier one and to make
it more effective, and second because the words which it would be
necessary to reject to give effect to the other view were not
originally in the amendatory act, but were inserted in it by way of
amendment while it was in process of adoption (Cong.Rec. 57th
Cong., 1st Sess., vol. 35, pt. 7, p. 7300;
id., 2d Sess.,
vol. 36, pt. 3, p. 2268), thus making it certain that, without
them, the act would not express the will of Congress.
For these reasons, it must be held that the original act, as
enlarged by the amendatory one, is intended to embrace all
locomotives, cars, and similar vehicles used on any railroad which
is a highway of interstate commerce.
We come, then, to the question whether these acts are within the
power of Congress under the commerce clause of the Constitution,
considering that they are not confined to vehicles used in moving
interstate traffic, but embrace vehicles used in moving intrastate
traffic. The answer to this question depends upon another, which
is, is there a real or substantial relation or connection between
what is required by these acts in respect of vehicles used in
moving intrastate traffic and the object which the acts obviously
are designed to attain -- namely, the safety of interstate commerce
and of those who are employed in its movement? Or, stating it in
another way, is there such a close or direct relation or connection
between the two classes of traffic, when moving over the same
railroad, as to make it certain that the safety of the interstate
traffic and of those who are employed in its movement will be
promoted in a real or substantial sense by applying the
requirements of these acts to vehicles used in moving the traffic
which is intrastate as well as to those used in moving that which
is interstate? If the answer to this question, as doubly stated, be
in the affirmative, then the principal question must be answered in
the same way. And this is
Page 222 U. S. 27
so not because Congress possesses any power to regulate
intrastate commerce as such, but because its power to regulate
interstate commerce is plenary, and competently may be exerted to
secure the safety of the persons and property transported therein
and of those who are employed in such transportation, no matter
what may be the source of the dangers which threaten it. That is to
say, it is no objection to such an exertion of this power that the
dangers intended to be avoided arise, in whole or in part, out of
matters connected with intrastate commerce.
Speaking only of railroads which are highways of both interstate
and intrastate commerce, these things are of common knowledge: both
classes of traffic are at times carried in the same car, and when
this is not the case, the cars in which they are carried are
frequently commingled in the same train and in the switching and
other movements at terminals. Cars are seldom set apart for
exclusive use in moving either class of traffic, but generally are
used interchangeably in moving both, and the situation is much the
same with trainmen, switchmen, and like employees, for they
usually, if not necessarily, have to do with both classes of
traffic. Besides, the several trains on the same railroad are not
independent in point of movement and safety, but are
interdependent, for whatever brings delay or disaster to one, or
results in disabling one of its operatives, is calculated to impede
the progress and imperil the safety of other trains. And so the
absence of appropriate safety appliances from any part of any train
is a menace not only to that train, but to others.
These practical considerations make it plain, as we think, that
the questions before stated must be answered in the
affirmative.
Affirmed.
