What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "economic activity and regulation".

Opinion:
Sol DIAMOND, Appellant, v. The CENTRAL RAILROAD COMPANY OF NEW JERSEY.
No. 11409.
United States Court of Appeals, Third Circuit.
Argued Jan. 4, 1955.
Decided Jan. 12, 1955.
Milford J. Meyer, Philadelphia, Pa. (Meyer, Lasch, Hankin & Poul, Philadelphia, Pa., on the brief), for appellant.
John R. McConnell, Philadelphia, Pa. (Morgan, Lewis & Bockius, Philadelphia, Pa., on the brief), for appellee.
Before MARIS, GOODRICH and STA-LEY, Circuit Judges.
PER CURIAM.
The sole question raised on this appeal by the plaintiff from what he regards as an inadequate judgment in a suit for personal injuries under the Federal Employers’ Liability Act, 45 U.S.C.A. § 51 et seq., is whether the trial judge erred in submitting the question of contributory negligence to the jury. The plaintiff concedes that the trial judge’s instructions on this question were proper if there was evidence from which the jury might find the plaintiff guilty of contributory negligence over and above his assumption of the risk of his employment. Our examination of the record satisfies us that there was such evidence. We accordingly find no error.
The judgment of the district court will be affirmed, each party to bear its own costs in this court.
