The Central Railway has made significant progress in its Mumbai track replacement project, installing 65 km of new tracks since April 2024. The initiative, driven by the aging infrastructure of existing tracks, aims to replace 126 km of tracks by April 2025, according to reports from the source. The project focuses on critical routes within the Mumbai division, including: • Chhatrapati Shivaji Maharaj Terminus (CSMT) to Kalyan • Kalyan to Lonavala • Kalyan to Igatpuri • Panvel corridor These sections collectively handle the daily movement of 1,810 local trains and 250–300 mail and express trains, making the upgrades essential for safe and efficient operations. The harsh coastal climate and humidity in Mumbai accelerate track wear and tear, necessitating frequent maintenance. While regular upkeep is conducted, full track replacement is carried out based on lifecycle assessments. • The replacement work is done during short operational intervals called “blocks,” lasting a few hours. • Teams of 30 railway officials, equipped with specialised machinery, replace 200–600 meters of track during each block. • Old rails are removed, and new ones are installed, welded, and aligned to meet precise operational standards. This track replacement project is part of broader efforts by Indian Railways to modernise infrastructure and ensure safety across its network. With nearly 97% of India’s broad gauge routes electrified, these upgrades reflect the railway's focus on long-term sustainability and efficiency. (Financial Express)
