Summary: The Enhanced Personnel Safety Motion Indicator for Railway Stabling Depot Hazardous Zones is designed to enhance safety in areas with limited visibility, where the risk of oversight and lack of cautionary measures poses potential dangers to personnel. If a train operator fails to detect personnel in these blind spots, accidents may occur. To mitigate these risks, the prototype integrates a Passive Infrared (PIR) Sensor to detect personnel presence, activating a Rotating LED and an Audible Alarm to alert both the personnel and train operator. Moreover, a camera surveillance system provides real-time monitoring, transmitting live footage to the train operator’s display monitor and the personnel overseeing the stabling area. Comprehensive testing was conducted to ensure the system’s effectiveness. The researchers performed various assessments, including sensor activation, detection accuracy at different angles, LED visibility in day and night conditions, audibility tests, push-button functionality, battery capacity, and CCTV clarity in different lighting conditions. Results showed that the PIR sensor effectively detects movement within a 2 to 6-meter range, an ideal distance for triggering safety measures. The Rotating LED is visible up to 16 meters, ensuring train operators are promptly alerted to take necessary precautions, including verifying personnel status via CCTV before proceeding. The prototype was evaluated by 10 university professors and 20 students using TUP’s standard evaluation instrument for functionality, usability, and efficiency. It received an overall mean score of 4.57, indicating that it is functional, user- friendly, and easy to operate. In conclusion, the Safety Motion Indicator has been proven effective in enhancing railway depot safety, based on rigorous testing and evaluation.

The Enhanced Personnel Safety Motion Indicator for Railway Stabling Depot Hazardous
Zones is designed to enhance safety in areas with limited visibility, where the risk of
oversight and lack of cautionary measures poses potential dangers to personnel. If a train
operator fails to detect personnel in these blind spots, accidents may occur. To mitigate
these risks, the prototype integrates a Passive Infrared (PIR) Sensor to detect personnel
presence, activating a Rotating LED and an Audible Alarm to alert both the personnel
and train operator. Moreover, a camera surveillance system provides real-time
monitoring, transmitting live footage to the train operator’s display monitor and the
personnel overseeing the stabling area. Comprehensive testing was conducted to ensure
the system’s effectiveness. The researchers performed various assessments, including
sensor activation, detection accuracy at different angles, LED visibility in day and night
conditions, audibility tests, push-button functionality, battery capacity, and CCTV clarity
in different lighting conditions. Results showed that the PIR sensor effectively detects
movement within a 2 to 6-meter range, an ideal distance for triggering safety measures.
The Rotating LED is visible up to 16 meters, ensuring train operators are promptly
alerted to take necessary precautions, including verifying personnel status via CCTV
before proceeding. The prototype was evaluated by 10 university professors and 20
students using TUP’s standard evaluation instrument for functionality, usability, and

efficiency. It received an overall mean score of 4.57, indicating that it is functional, user-
friendly, and easy to operate. In conclusion, the Safety Motion Indicator has been proven

effective in enhancing railway depot safety, based on rigorous testing and evaluation.
