en.Wedoany.com Reported - Central Railway's Nagpur Division has successfully deployed and commissioned a modern distributed electronic interlocking system at Sevagram station, as part of the third and fourth line expansion project on this route. This signaling system upgrade aims to enhance signal reliability, operational safety, and train handling capacity on this critical railway corridor, while supporting the operation of longer freight and passenger trains.
The distributed electronic interlocking system, supplied by KYOSAN, replaces the 26-year-old Siemens panel interlocking (PI) system. This upgrade marks a significant technological leap, expected to substantially improve the operational efficiency, safety, and maintainability of railway signaling infrastructure, and play a key role in enhancing train operation efficiency and capacity on Central Railway's vital railway corridor.
As part of the upgrade, extensive yard remodeling was completed at Sevagram station. During the remodeling, two ground control panel (GF) points were eliminated to reduce reliance on manual intervention and improve train operation safety standards. Meanwhile, UDL-1 and UDL-3 lines were introduced to enhance traffic handling capacity and streamline train movement within the yard.
This upgrade has significantly increased the reception capacity of crossing stations on multiple railway lines, enabling the station to handle longer trains and improve transport efficiency. Specific capacity improvements include: the reception capacity of the Up Loop crossing station increased from 705 meters to 780.181 meters, a gain of 75.181 meters; the Down Main Line crossing station reception capacity increased from 585 meters to 926.212 meters, a substantial gain of 342.212 meters; another Up Loop crossing station reception capacity increased from 698 meters to 780 meters, a gain of 82 meters; the Up/Down Common Loop crossing station reception capacity has been increased to 854 meters; and the Down Loop crossing station reception capacity has been increased to 835.902 meters.
This advanced distributed electronic interlocking system provides modern centralized control and monitoring capabilities, promising faster response times and higher signaling equipment reliability. The upgraded infrastructure will help reduce operational delays and improve overall network efficiency. As freight and passenger demand grows in the region, the improved yard layout and signaling system will enable Central Railway to efficiently handle longer trains while maintaining higher operational safety standards. The successful commissioning of this system reflects Nagpur Division's ongoing strategy to advance the application of modern railway technologies and infrastructure modernization initiatives.
