Railroad v. Johnson was a case heard by the United States Supreme Court in 1875. The case involved a dispute between the Railroad Company and Johnson, a farmer, over the ownership of a strip of land. The Railroad Company claimed that the land was part of a right-of-way granted to them by the state of Illinois. Johnson argued that the land was part of his farm and that the Railroad Company had no right to it. The Supreme Court ruled in favor of Johnson, finding that the Railroad Company had no right to the land. The Court held that the Railroad Company had failed to prove that the land was part of the right-of-way granted to them by the state of Illinois. The Court also held that Johnson had a valid claim to the land, as he had been in possession of it for many years prior to the Railroad Company's claim. The decision in Railroad v. Johnson established that the Railroad Company had no right to the land in question and that Johnson had a valid claim to it. The decision also established that the Railroad Company had failed to prove that the land was part of the right-of-way granted to them by the state of Illinois. This case is an important precedent for property rights and the rights of landowners.

In Railroad v. Johnson, the United States Supreme Court was tasked with determining whether a railroad company could be held liable for damages to an individual's property caused by sparks from its locomotive. The majority opinion found that the railroad had not acted negligently and thus could not be held liable for any damages incurred. Justice Field dissented, arguing that it was reasonable to expect a railway company to take precautions against such damage and therefore they should have been held responsible in this case. He argued that since there were no laws or regulations at the time requiring them to do so, it would be unfair if they were absolved of all responsibility simply because of their lack of foresight in taking preventative measures against potential harm resulting from their operations. Furthermore, he noted that even though there may have been some uncertainty as to what constituted negligence on behalf of the railway company at the time due to a lack of legal precedent on this issue, common sense dictated that certain safety precautions should have been taken regardless which would likely have prevented any damage occurring in this instance.
