Delhi-Howrah train speed boost as Railways upgrades 73-year-old UP bridges

According to Railways, ORN-2 refers to Category II bridge structures identified during inspections as requiring either maintenance or rehabilitation.

As part of this project, the old Broad Gauge Main Line (BGML) loading girders were removed and replaced with modern 25-ton welded steel plate girders and H-beam steel sleepers. Additionally, the bridge’s sub-structure (piers) underwent concrete jacketing, thereby significantly enhancing both its service life and load-bearing capacity, it said.

The NCR further added that the entire undertaking was executed through a special drive conducted between March 12 and March 20, 2026, during which all 8 spans were successfully replaced in record time.

Bridge number 46 on Chopan-Chunar rail section upgraded

It also upgraded Bridge No. 46, which was built to outdated 1953 standards and had required speed restrictions for trains crossing it. The bridge has now been fitted with 25-tonne welded steel girders, making it capable of handling future heavy freight and high-speed passenger services.

“Previously, a permanent speed restriction of 30 kilometers per hour was imposed on these bridges for safety reasons; this restriction will now be lifted. This will lead to improved punctuality for trains.

The installation of modern girders with a 25-ton loading capacity will facilitate the smooth operation of heavy freight trains, thereby boosting the railway’s revenue and logistical capabilities. Due to modern steel sleepers and jacketing technology, the structural integrity of these bridges now aligns with international safety standards,” it said.
