What legislation was enacted to regulate railroads in the U.S.?

The Interstate Commerce Act was enacted in 1887 as a response to growing concerns about the monopolistic practices of railroads and the need for regulation of freight rates. This legislation aimed to ensure fair pricing, prevent discriminatory practices, and promote competition among railroad companies. It established the Interstate Commerce Commission (ICC), which was tasked with overseeing the railroad industry and enforcing regulations. The passage of the Interstate Commerce Act marked the first time the federal government took an active role in regulating private industry for the public good, setting a precedent for future regulatory actions in other sectors.

Other options such as the Transportation Safety Act, Railroad Regulation Act, and Federal Rail Safety Act either do not correspond to legislation specifically regulating railroads or pertain to different aspects unrelated to the economic regulation and oversight intended by the Interstate Commerce Act.
