Train accidents often occur because of human error, problems with the track, equipment, and/or signal. Oftentimes many people are injured because of train accidents. There are many factors that lead to a railroad accident and there are many people who may be liable. It is the responsibility of the railroad company to maintain the tracks and the train. But truck and car drivers are responsible if they do not follow laws that are intended to protect against accidents. People who are injured in train accidents may be compensated for their injury, lost income, and pain and suffering.
