The Chinchwad-Khadki railway section has undergone a remarkable transformation with the implementation of an advanced automatic signalling system. This upgrade brings a multitude of benefits to train operations, safety, and travel time. Let’s delve into the prominent features that make the Chinchwad-Khadki Automatic Signalling system a game-changer in the realm of railway transportation.
- Improved Trains Headway: One of the primary advantages of the Chinchwad-Khadki Automatic Signalling system is its ability to enhance trains’ headway. With precise control and coordination of train movements, the system optimizes the spacing between trains, allowing for a smoother and more efficient flow of rail traffic.
- Enhanced Train Safety: The new system incorporates an Auxiliary Warning System for 21 UP and DN signals, bolstering train safety. This system acts as an additional layer of protection, reducing the risk of collisions and ensuring a safer rail journey for passengers.
- Multi Section Digital Axle Counter (MSDAC): The implementation of MSDAC for track vacancy detection has led to a significant reduction in travel time. By accurately detecting track occupancy, trains can proceed with confidence, knowing that the track ahead is clear, ultimately resulting in faster journeys.
- Optimized Signal Placement: The installation of signals at 1 km intervals not only improves section capacity but also reduces travel time. This strategic placement allows for efficient train movement and better utilization of the railway infrastructure.
- Auxiliary Warning System (AWS): The inclusion of AWS in EMU (Electric Multiple Unit) trains and track lines ensures that trains operate at safe speeds. This feature becomes especially crucial when approaching yellow signals, facilitating emergency brake application and preventing accidents.
- Automated Signal Clearance: The Chinchwad-Khadki Automatic Signalling system eliminates the need for manual signal clearance by utilizing a train’s movement. As a train passes each signal, the rear signal automatically changes from red to yellow, indicating safe passage for the next train. This innovation enhances the safety and efficiency of train operations.
- Dual Track Vacancy Detection: The incorporation of Multi Section Digital Axle Counters (MSDAC) with international Safety Integrity Level (SIL) 4 ensures a robust and reliable track vacancy detection system. This feature enhances overall safety and reliability, minimizing the risk of track-related incidents.
- Modern Level Crossing Gates: The system brings modernization to level crossings, with the installation of motor-operated barriers equipped with new interlocking mechanisms. This upgrade enhances the safety of road-rail intersections.
- Electronic Control LED Signals: All 21 new automatic signals are equipped with electronic control LED signals, ensuring high visibility and clarity for both train operators and pedestrians.
- Real-Time Data Management: The introduction of real-time Datalogger systems in three relay huts enables efficient data management and control. This networking system connects divisional and headquarters control, enhancing operational oversight.
- Fire Detection Alarm System: Safety is further reinforced with the implementation of fire detection alarm systems in three relay huts, providing early warnings in case of fire emergencies.
- Track Circuits for Safety: A total of 43 coded Audio Frequency Track Circuits (AFTC) have been commissioned for track vacancy detection, adding an extra layer of safety to train operations.
The Chinchwad-Khadki Automatic Signalling system is a testament to modernizing railway operations, prioritizing safety, and enhancing passenger experience. With its comprehensive features, this system contributes to a more efficient, secure, and reliable railway network.
