delivered the opinion of the Court.
Thе company sued the attorney general and the prosecuting attorneys of two circuits of Arkansas to enjoin the enforcement of statutes of that State regulating freight train crews and switching crews upon the claim that they are repugnant to the Constitution аnd laws of the United States. On the complaint and supporting affidavits the plaintiff applied for a temporary injunction. Defendants moved to dismiss. The court, consisting of a circuit judge and two district judges, held the complaint insufficient to show any ground for relief and dismissed the case. 42 F. (2d) 765.
The statutes so assailed are Laws, 1907, Act 116, and Laws, 1913, Act 67 (§§ 8577-8579 and 8583-8586, Crawford & Moses’ Digest, 1921) which so far as here material *251 are printed in the margin. 1 The earlier Act requires railroad carriers whose lines are not less than 50 miles in length to have not less than three brakemen in every crew of freight trains of 25 cars or more. The later Act rеquires not less than three helpers in switch crews in yards in cities of the first and second class operated by companies having lines of 100 miles or more.
The complaint asserts that each of these Acts violates the commerce clause of the Federal Constitution and the
*252
due process and equal protection clauses of the Fourteenth Amendment and is repugnant to the Interstate Commerce Act as amended in 1920
2
and to the Railway Labor Act.

But they have been held valid by this court as against the claim of repugnancy to these clаuses of the Constitution. See
Chicago, R. I. & Pac. Ry. Co.
v.
Arkansas,
The first of these cases was decided in 1911. The court held that the Act of 1907 is not a regulation of interstate commerce and that upon its face it must be taken as having been enacted in aid of, and for the protection of those engaged in, such commerce. It said that Congress might have taken entire charge of the subject, but that it had not done so and had not enacted regulations in respect of the number of employees to whom might be committed the management of interstate trаins and that until it does the statutes of the State, not in their nature arbitrary, must control. The court found that, while under the evidence there was admittedly room for controversy as to whether the statute was necessary, it could not be said that it was so unreasonable as to justify the court in adjudging it an arbitrary exercise of power. And it held that, being applicable alike to all belonging to the same class, there was no basis for the contention that it denied the company equal protection of the laws. The principles gоverning that decision were followed in the later case, decided in 1916, which upheld the Act of 1913. Both Acts were sustained as valid exertions of police power for the promotion of safety of employees and others.
The plaintiff says that, since thesе decisions, Congress has occupied the field and has delegated to the Commis *253 sion and Labor Board full authority over the subject and that the state laws under consideration are repugnant to the comprehensive scheme of federal regulation рrescribed by the Interstate Commerce Act as amended and conflict with §§ 1 (10) and (21), 13, 15 and 15a thereof and with the spirit of the Railway Labor Act of 1926.
It maintains that the allegations of the complaint together with the facts set forth in the affidavits show that, when applied to оperating conditions on its lines in Arkansas, these state laws are arbitrary and violative of the Federal Constitution and laws. But the affidavits filed in support of the application for a temporary injunction may not be considered in determining whether the complаint states facts sufficient to constitute ground for relief.
Leo
v.
Union Pac. Ry. Co.,
The substance of the pertinent allegations of the complaint follows:
Present railroad operating conditions on plaintiff’s railroad in Arkansas and elsewhere, and on railroads generally in this country, diffеr from those that existed in 1907 and 1913 when these laws were passed. Roads and equipment have been so improved that longer and heaver trains may be operated more safely now than much smaller trains could then be operated. It is standard practicе of railroads “ wherever the density of traffic is sufficient, except in the State of Arkansas, to operate freight and passenger trains and switch engines with crews consisting of less than the extra switchmen [meaning one less than required by the 1913 Act] and extra brakemen [meaning one less than required by the 1907 Act] provided by the Arkansas laws.”
Freight trains and switch engines are safely operated on lines similar to those of plaintiff “ wherever the traffic *254 and circumstances make such operation advisable, without such extra switchmen and extra brakemen.” By increаsing lengths of their freight trains, the plaintiff and other railroads in States “ where such extra brakemen and extra switchmen are not [by law] required ” have been able to effect great economies. But by the Arkansas laws plaintiff is compelled there to employ more than the standard crew and to pay for services and time not needed or used for the operation of its. freight trains.
The standard agreement between plaintiff and the Brotherhood of Railroad Trainmen provides for a switch crew consisting of a foreman and two helpers and “ also provides for a . . . freight train crew, in through and irregular freight service, of a conductor and two brakemen.” Other railroads have similar agreements with the Brotherhood “ with the exception of the service in States with laws similar to the abоve laws of the State of Arkansas.”
And it is alleged that, if plaintiff were permitted to operate its freight trains without the extra brakemen required by the Act of 1907, its expenses would be reduced by $350,000 per year; and, if permitted to operate its switch engines without the extra helper required by the Act of 1913, its expenses would be reduced $250,000 per year.
The complaint contains much by way of argument, assertions as to questions of law together with inferences and conclusions of the pleader as to matters of fact. These arе not deemed to be admitted by motion to dismiss.
Equitable Life Assurance Society
v.
Brown,
There is no showing that the dangers against which these laws were intended to safeguard emplpyеes and the public no longer exist or have been lessened by the improvements in road and equipment or by the changes in operating conditions there described. And, for aught that appears from the facts that are alleged, the same or greater need may now exist for the specified number of brakemen and helpers in freight train and switching crews. It is not made to appear that the expense of complying with the state laws is now relatively more burdensome than formerly. Greater train loading tends to lessen operating expenses for brakemen. There is no statement as to present efficiency of switching crews compared with that when the 1913 Act was passed, but it reasonably may be inferred that larger cars and heavier loading of today make for a lowеr switching expense per car or ton. While cost of complying with state laws enacted to promote safety is an element properly to be taken into account in determining whether such laws are arbitrary and repugnant to the due process clause of the Fourteenth Amendment,
(Lehigh Valley R. Co.
v.
Commissioners,
Has Congress prescribed, or authorized the Interstate Commerce Commission to regulate, the number of brakemen to be employed for the operation of freight trains or the number of helpers to be inсluded in switching crews?
In the absence of a clearly expressed purpose so to do Congress will not be held to have intended to prevent the exertion of the police power of the States for the regulation of the number of men to be emplоyed in such crews.

v.
Colorado,
No analysis or discussion of the provisions of the Railway Labor Act of 1926 is necessary to show that it does not conflict with the Arkansas statutes under consideration.
Decree affirmed.
