Pune-Lonavala Railway section achieves full automation

The successful implementation of the Automatic Signalling system between Khadki and Pune on the Pune-Lonavala railway section is a significant milestone. This accomplishment covers a distance of 5 route kilometres and signifies the completion of the entire Automatic Signalling infrastructure along the 64-kilometer Pune-Lonavala section. This achievement ushers in a new era in railway operations, bringing about transformative changes.

The recently introduced enhancements in the Khadki-Pune section encompass several notable aspects. These include the activation of two additional automatic signals, modifications in seven existing signals, and the implementation of nine new track circuits. 

To accommodate the changes in signal aspects, significant alterations were made within the Pune Route Relay Interlocking (RRI) system. Furthermore, the infrastructure at Khadki has been fortified with the addition of eleven auxiliary warning system (AWS) track magnets and the installation of Electronic Interlocking, which now covers 112 routes.

The project further encompassed the integration of four lines within the Military yard, thereby improving the effectiveness of the already established four main lines. Moreover, the replacement of 35-point machines, 18 main signals, and 14 shunt signals demonstrated a dedication to establishing a technologically advanced and resilient railway network.

The project encompassed a wide range of elements, such as the transformation of Alstom track circuits into DC track circuits for a total of 34 circuits. Additionally, it involved the installation of 20 new DC track circuits in the Khadki and Khadki-Shivajinagar automatic section. Furthermore, new wiring was implemented for Level Crossing Gate numbers 63 and 62A, while dual detection was introduced for all track circuits at Khadki. Lastly, display units were provided for automatic signaling in the Visual Display Unit (VDU) room.

The Electronic Interlocking room has been equipped with a fire alarm system consisting of 53 detectors and an aspiration system, prioritizing safety measures. Additionally, an auto-changeover arrangement is in place for the standby conventional power supply system, guaranteeing uninterrupted operations.

The accomplishment signifies a notable advancement in railway technology, improving the capacity of the Pune-Lonavala section and reducing the reliance on human intervention in train operations. The inclusion of this section expands the already established Automatic Signalling system in the Central Railway, covering a total distance of 339.14 kilometers across Mumbai, Bhusawal, Nagpur, and Pune divisions.

There are ongoing developments in the Central Railway network, which involve the installation of an additional 61.27 kilometers of Automatic Signalling systems. These systems are expected to be operational in the current financial year and will enhance train mobility, increase operational speeds, and reduce congestion in critical sections. Additionally, significant shadow works have been carried out in the Pune division, which have comprehensively strengthened the railway’s infrastructure.
