In the case of Chicago, Milwaukee and St. Paul Railway Company v. Solan (1897), the U.S Supreme Court ruled in favor of the railway company. The dispute arose when a train owned by the railway company collided with a wagon driven by Solan at an intersection where there were no warning signs or signals to alert drivers about incoming trains. As a result of this accident, Solan suffered severe injuries and sued for damages on grounds that it was due to negligence on part of the railway company for not providing adequate warnings at intersections which led to his injury. The court held that while railways have certain obligations towards public safety, they are not required under law to provide specific types of warnings such as bells or flags at every crossing point along their tracks unless mandated by local laws or regulations. In absence of any such requirement in this particular location, it was deemed unreasonable to hold them responsible for failing to do so. Furthermore, it was also noted that even if there had been some form warning system installed at said intersection; given how fast both parties were moving prior collision - it would've likely made little difference in preventing accident from happening thus absolving them from liability claims raised against them.

In the dissenting opinion for Chicago, Milwaukee and St. Paul Railway Company v. Solan, Justice Harlan argued that the majority's decision was inconsistent with previous rulings of the court regarding state regulation of interstate commerce. He contended that states should have some authority to regulate matters within their borders even if they affect interstate commerce indirectly. In this case, he believed that Minnesota had a right to establish reasonable regulations for railway companies operating in its territory as long as it did not interfere directly with Congress' power over interstate commerce or discriminate against out-of-state entities. The justice also expressed concern about potential negative implications of limiting state regulatory powers on public welfare and safety issues related to railroads such as rates and services provided by them.
