Problems with the track and human error are two of the most common causes
of train derailment. Track monitoring and inspections are essential to
prevent derailments caused by defective tracks and switches. Proper training
and safety standards can help to prevent human error, such as improper
handling of a train or excessive speed. A new system called positive train
control (PTC) is being implemented across the country as a part of the
Rail Safety Improvement Act of 2008, which uses GPS to track a train’s
location and speed and can signal whether it needs to be slowed down.
All of these things can help prevent train derailments.
