In a large boost to obstruction infrastructure, the Mysuru Division of the South Western Railway completed the way electrification of the Sakleshpur–Subramanya Road Ghat Section, reckoned to beryllium 1 of the astir hard terrain connected the Indian Railway network.
A palmy proceedings tally of the electrical locomotive was besides completed connected December 28, marking the culmination of a analyzable engineering effort successful the landslide-prone Western Ghat region.
The railway authorities described the completion of the task arsenic a large milestone that volition springiness obstruction infrastructure a fillip.
The Ghat Section comprises a 55 km-stretch betwixt Sakleshpur and Subramanya Road, which is besides 1 of the astir technically challenging sections of Indian Railways and is connected the Hassan-Mangaluru route, said the authorities.
The way includes a steep 1-in-50 gradient, which means the way rises by 1 metre for each 50 metres of region covered. It besides includes 57 tunnels, 258 bridges, and 108 crisp curves, and is highly prone to landslides, making execution of electrification works exceptionally complex.
Girish Dharmaraj Kalagonda, divisional commercialized manager, Mysuru, said the electrification enactment commenced connected December 1, 2023 and the task was completed astatine a outgo of ₹93.55 crore.
Explaining the challenges progressive successful the execution of the task, Mr. Girish said that fixed the steep gradients and inclines successful the terrain, specialised instrumentality and robust engineering designs were deployed to support due hostility and stableness of the overhead system.
Heavy monsoon, predominant landslides, ungraded erosion, and rockfalls, were different issues faced by the workers during proscription of materials by obstruction to distant and inaccessible locations, helium added.
“The task progressive the operation of 5 switching stations on the way and overhead electrification of the full section. The overhead instrumentality has been designed for a maximum velocity of 120 kmph, with the maximum span betwixt 2 traction poles constricted to 67.5 metres, ensuring information and operational reliability,” said Mr. Girish.
Detailed geological surveys for some lined and unlined portions of tunnels were conducted by the National Institute of Rock Mechanics and Bangalore University. To guarantee semipermanent information and stability, assorted tests were conducted to verify due grouting and anchoring of bolts, according to the authorities.
Given the steep gradients and constricted availability of abstraction for information features, the Commissioner of Railway Safety (CRS) imposed stringent operational restrictions during the execution of the enactment which added to the complexity of the task, they added.
With the palmy completion of electrification and electrical locomotive trial, the full Ghat Section is present acceptable for electrical traction, enabling cleaner, energy-efficient, and cost-effective bid operations. The authorities said this accomplishment marks an important measurement towards Indian Railways’ nonsubjective of 100% electrification and reinforces its committedness to gathering sustainable and resilient obstruction infrastructure successful challenging terrains.
