Eastern Railway Pulls Off Engineering Marvel: Two-Level Crossings Eliminated in a Single Mega Block
Kolkata, March 2, 2026:
For the thousands of daily commuters on the Sealdah division, the rhythmic clatter of the tracks often masks the monumental efforts required to keep the lifeline of the suburbs running safely. In a display of relentless commitment to passenger safety and operational efficiency, Eastern Railway (ER) engineers worked through the clock on Sunday, 1st March 2026, to achieve a rare feat of civil engineering: the simultaneous elimination of two-level crossing gates.
The elimination of Lavel Crossing gate No.-165/E (between Bhagwangola-Krishnapur) and Lavel Crossing gate No.-154/E (between Jiaganj-Bhagwangola) marks a significant milestone in ER’s mission to remove surface constraints that hinder both train speed and public safety. By replacing these gates with Limited Height Subways (LHS), the railways have effectively removed the risk of road-rail collisions while ensuring a smoother journey for passengers.
A Precision Operation
The scale of the operation was massive. To minimize disruption, the Sealdah (SDAH) division executed a “Mega Block,” deploying a small army of machinery and personnel. At Lavel Crossing gate No.-165/E, a 5.5-hour block saw the installation of 10 massive RCC boxes and 9 base slabs using two 350-ton road cranes and six Poclains. Simultaneously, at Lavel Crossing gate No.-154/E, 12 RCC boxes and 11 base slabs were positioned with surgical precision.
Pioneering Waterproofing Technology
Setting a new benchmark for infrastructure longevity, Eastern Railway introduced high-end waterproofing for the first time at these sites. To ensure the subways remain bone-dry even during the monsoon, engineers applied a multi-layered defense system:
- Polyurea Surface Coating: A robust barrier protection.
- HDPE Sheets with Geotextiles: For superior separation function for drainage.
The “Shadow Block” Advantage
True to the philosophy of “not wasting a single minute,” ER utilized the “Shadow Block”—performing vital maintenance while the tracks were already closed for the LHS work.
While the cranes were lifting boxes, MFI machines were engaged in the through-tamping of two important Points & Crossings at Jiaganj yard. Additionally, 7 km of plain track tamping was completed in the Bhagwangola – Jiaganj – Murshidabad section. Safety was further bolstered by the welding of Railway track joints with high precision and the installation of improved Switch Expansion Joints at Krishnapur for buffering temperature variation of track length.
Powering the Future
The electrical department was equally active. Four Tower Wagons swarmed the section to overhaul the Overhead Equipment (OHE). Notable works included the replacement of four small chair bracket assemblies with long chair brackets at Pirtala and the completion of Periodical Overhaul for six single cantilevers. From adjusting catenary staggers to overhauling ATDs (Auto Tensioning Devices), every component was fine-tuned to ensure that when the first train rolled over the new boxes, it did so under a perfect power supply.
This successful “Mega Mission” underscores Eastern Railway’s proactive stance. By eliminating bottlenecks and integrating cutting-edge technology, the railway isn’t just maintaining tracks; it is engineering a safer, faster, and more reliable future for the people of Bengal.
