Metro Upgrades to Aluminum Third Rail

08 Aug 2024 CW Team

The Kolkata Metro is set to replace its existing steel third rail with an aluminum one to enhance efficiency and performance. This upgrade is part of a broader initiative to modernize metro infrastructure and improve service reliability.

The decision to switch to aluminum is driven by several factors. Aluminum is lighter than steel, which will reduce the overall weight of the rail system, leading to decreased strain on supporting structures and potentially lowering maintenance costs. Additionally, aluminum?s superior conductivity will improve the efficiency of power transmission, contributing to better energy use and enhanced performance of metro trains.

The new aluminum rails are expected to offer greater durability and resistance to environmental factors, which will further extend the lifespan of the infrastructure. The transition is also anticipated to reduce operational disruptions and improve the overall safety and reliability of the metro service.

This move aligns with ongoing efforts to modernize urban transport systems and provide more efficient and sustainable public transportation options. By upgrading the third rail system, Kolkata Metro aims to enhance passenger experience and operational efficiency, paving the way for future growth and development.

Overall, the switch to aluminum rails represents a significant advancement in metro infrastructure, contributing to a more reliable and efficient transit system.
