All operators of public transportation, often called 'common carriers', are responsible for taking all steps necessary to protect the safety of their passengers. There are strict federal and state laws governing the safe operation of trains, and federal authorities usually investigate any serious accidents that occur. Less serious injuries involving trains, such as a slip and fall accident occurring while riding a train, may result in a liability claim if it can be shown that the train operator didn't provide sufficient safety features or adequate warnings of the danger. Railroad companies are also responsible for providing safe and secure facilities for boarding and leaving the train, and for luggage storage. Other accidents involving trains include collisions between trains and vehicles at crossings. Generally, the driver of a vehicle is responsible for exercising extreme care when driving over railroad crossings, but a liability issue may result if it can be shown that the railroad company was negligent in providing adequate warning signage or otherwise failed to take reasonable safety precautions. If you've been in an accident involving a train or other form of public transportation, consult an attorney specializing in personal injury law.
