Nagpur Metro Phase II enters track-laying stage

Nagpur Metro Phase II has entered the track-laying stage, with MahaMetro starting work on the Kamptee stretch of Reach-2.

Around 2 km of track has been laid so far, marking the transition from civil construction to railway systems work on the upcoming Metro network. The track-laying began after completion of viaduct and segment erection on the available stretch.

MahaMetro plans to begin track-laying on other reaches in phases this year as more viaduct stretches are completed.

The tracks use a redesigned fastening system that MahaMetro said will reduce construction costs, improve flexibility and minimise vibrations. The system has been approved by the Research Designs and Standards Organisation (RDSO) of Indian Railways, reported The Times of India.

The redesigned system uses two holes instead of the earlier four-hole arrangement to fasten the track to the concrete plinth.

Re-engineering has reduced the size of the base plate and the width of the plinth, resulting in savings in track-laying costs.

MahaMetro has also introduced specially designed double rubber pads to improve flexibility and reduce vibrations generated by train movement. The system is expected to lower stress on the tracks and improve their durability over their operational life.

To minimise installation errors, MahaMetro has adopted a gauge-based ‘Go-No Go’ checking system.

The work is being carried out under an ISO-certified Integrated Management System covering quality, safety and environmental standards, reported The Times of India.

MahaMetro managing director Shravan Hardikar recently inspected the track-laying work and reviewed the systems being adopted.

He discussed measures with officials to minimise track wear and tear during operations and directed them to focus on long-term durability.

The start of track-laying marks a key milestone for Phase II, with sections where viaduct construction has been completed now moving towards systems installation, followed by testing and commissioning.
