Question

1) This Supreme Court case ruled that RR's could e regulated because they served the public interest

2) Whe another Supreme Court case ruled that states could not regulate RR's, Congress passed this act to provide regulation

Answer 1

I'm guessing it would be: Wilson v. New, 243 U.S. 332 (1917)

The United States Supreme Court upheld the constitutionality of the Adamson Act in Wilson v. New, 243 U.S. 332 (1917).

The Adamson Act was a United States federal law passed in 1916 that established an eight-hour workday, with additional pay for overtime work, for railroad workers. This was the first federal law that regulated the hours of workers in private companies.

Congress passed the Act in order to avoid a nationwide strike. When the railroads refused to abide by the law while their court challenge to its constitutionality was pending, the railway unions began preparing again to strike. The Supreme Court's decision brought the employers around, however, and they entered into settlement discussions concerning implementation of the law.

Before that case, there was: United States v. Trans-Missouri Freight Association, 166 U.S. 290 (1897) which upheld that the Sherman Act (which was an antitrust measure that prohibited anticompetitive behavior in commerce) applied to the railroad industry, even though the U.S. Congress had enacted a comprehensive regime of regulations for that injury.

I couldn't find much else in my quick research... good luck.
