Helen Palsgraf was waiting at a train station platform for her train. While she was there, another train stopped and then began to leave.
A man who was late for the train ran to catch it and jumped on the moving train while holding a package. A train guard helped pull the man onto the train and another guard helped push him from behind. The man dropped his package. It fell and was run over by the train. The package was full of fireworks, which exploded.
The explosion caused some scales on the platform to fall, striking Palsgraf in the head, seriously injuring her.
Palsgraf sued the railroad for negligence by its employees during the event. The jury found for the plaintiff and the appellate division affirmed the judgment.
The railroad appealed to the New York high court.

1. Why was there no negligence on the part of the railroad?
2. Why is there no proximate cause in this situation?
