Pune, India – In a groundbreaking development, the Pune-Lonavala railway section has achieved full automation with the successful implementation of the Automatic Signalling system between Khadki and Pune. Covering a distance of 5 route kilometres, this accomplishment marks the completion of the entire Automatic Signalling infrastructure along the 64-kilometer Pune-Lonavala section, bringing transformative changes to railway operations.
Transformative Changes in Khadki-Pune Section
The recent enhancements in the Khadki-Pune section include the activation of two additional automatic signals, modifications in seven existing signals, and the implementation of nine new track circuits. These changes required significant alterations within the Pune Route Relay Interlocking (RRI) system. Additionally, the infrastructure at Khadki has been fortified with the addition of eleven auxiliary warning system (AWS) track magnets and the installation of Electronic Interlocking, covering 112 routes.
Strengthening Infrastructure and Technological Advancements
The project involved the integration of four lines within the Military yard, improving the effectiveness of the established four main lines. Notably, the replacement of 35-point machines, 18 main signals, and 14 shunt signals demonstrates a commitment to establishing a technologically advanced and resilient railway network.
The wide-ranging elements of the project included the transformation of Alstom track circuits into DC track circuits, totaling 34 circuits. It also involved the installation of 20 new DC track circuits in the Khadki and Khadki-Shivajinagar automatic section. Further enhancements included new wiring for Level Crossing Gate numbers 63 and 62A, dual detection for all track circuits at Khadki, and the provision of display units for automatic signaling in the Visual Display Unit (VDU) room.
Emphasizing Safety Measures
The Electronic Interlocking room is equipped with a fire alarm system comprising 53 detectors and an aspiration system, prioritizing safety measures. An auto-changeover arrangement for the standby conventional power supply system ensures uninterrupted operations, emphasizing the commitment to safety and reliability.
Advancements in Railway Technology
This achievement signifies a notable advancement in railway technology, enhancing the capacity of the Pune-Lonavala section and reducing reliance on human intervention in train operations. The expanded Automatic Signalling system in the Central Railway now covers a total distance of 339.14 kilometers across Mumbai, Bhusawal, Nagpur, and Pune divisions.
Ongoing developments in the Central Railway network involve the installation of an additional 61.27 kilometers of Automatic Signalling systems, expected to be operational in the current financial year. These systems will further enhance train mobility, increase operational speeds, and reduce congestion in critical sections. Additionally, significant shadow works in the Pune division have comprehensively strengthened the railway’s infrastructure.
