A subway accident isn't just about a train crashing or derailing. It's also about people being injured while waiting on the platform, falling onto the rails, falling on the stairwell that leads to the subway platform, running, and other mishaps that happen in a subway. A subway accident can result in very serious injuries. The most common types of injuries sustained in a subway accident are back/neck injuries, and soft tissue injuries (muscle strains, bruising, etc.). The most common reason for these types of subway injuries are slip-and-trip incidences that happen during boarding, unloading and while the train is in motion. In some states you are only allowed up to 90 days to file an injury claim with the proper authorities or your claim is not considered valid.
