This case involves an injury sustained by a passenger during the day at an outdoor light rail station in Washington. The plaintiff alleges that the train was stopped when the plaintiff walked to enter it, at which point the plaintiff slipped and became trapped between the platform and the train car. Allegedly, the train’s conductor failed to notice that the passenger was stuck, and proceeded to pull out of the station. Her lower extremities sustained serious injuries in the process. The defense contends that the light rail car was moving while the plaintiff attempted to walk into the car. The plaintiff seeks an expert that can evaluate the situation and determine if the train car was stopped at the time of the accident.
