Kolkata Metro Update: Aluminum third rail replaces steel at Maidan sidingKolkata Metro has successfully replaced the steel third rail at Maidan siding with a more efficient aluminum third rail on the night of September 14, 2024. This 200-meter upgrade, part of the North-South Metro (Blue Line) improvement project, follows a similar replacement at Girish Park siding completed on September 7. The...

The team, led by Deputy Chief Electrical Engineer Sumit Kayal, completed the work before 5:00 AM, ensuring smooth morning services. Aluminum rails are expected to reduce energy losses, increase train acceleration, improve operational efficiency, and reduce costs. Additionally, they will reduce carbon emissions by 50,000 tons over their lifetime, require less maintenance, and generate less heat in the tunnels.
Kolkata Metro ne 14 September, 2024 ki raat ko Maidan siding mein steel third rail ko replace karke usko aluminum third rail se badal diya hai, yeh zyada efficient hai. Yeh 200 meter ka upgrade North-South Metro (Blue Line) ko behtar banane ke project ka hissa hai aur yeh Girish Park...

Is kaam mein purane rails ko hataaya gaya aur GRP insulators par new aluminum rails install kiye gaye. Deputy Chief Electrical Engineer Sumit Kayal ke netrutva mein 50 staff ki team ne subah 5:00 baje se pehle yeh kaam pura kar liya, jisse subah ki metro services smoothly chalti rahi. Aluminium rails se energy losses kam hone ki ummeed hai, jisse train ki speed badhegi, operational efficiency badhegi, aur cost kam hoga. Iske alawa, yeh rails apni lifetime mein 50,000 tons carbon emission kam karenge, inki kam maintenance ki jarurat padegi, aur tunnels mein kam heat generate hoga, jisse metro system ko faida hoga.
