Positive Train Control (PTC) is an advanced safety system designed to prevent train accidents. It uses GPS, wireless radio, and computer technology to monitor train movements and ensure they operate within safe parameters. PTC can automatically slow down or stop a train if it detects potential hazards, such as excessive speed or unauthorized track changes. This system is particularly important for enhancing safety in the railroad industry. PTC aims to reduce the risk of collisions, derailments, and other incidents that can endanger passengers and crew. By implementing PTC, railroads can improve overall operational safety and efficiency.
