What are "Train Approach Warning Systems" used for?

Train Approach Warning Systems are specifically designed to provide early warnings of trains approaching work zones, which is critical for enhancing the safety of roadway workers. These systems use various technologies, such as audio alarms, visual signals, or electronic displays, to alert workers of an incoming train well before it arrives. The intention is to give workers sufficient time to vacate the area safely, thereby reducing the risk of accidents and ensuring that they have the necessary time to respond appropriately to the presence of trains in their vicinity.

The focus of these systems is on worker safety as trains can approach quickly and may not be visible until they are very close. This proactive approach to warning workers can significantly decrease the likelihood of collisions or dangerous situations.
