Metro Railways Towards A Sustainable Energy Bank

 The Metro Railways have brought it to the notice of the society that:

Metro Railway, Kolkata has achieved the first milestone, after the successful completion of the replacement of Steel Third Rail by Highly Conductive Aluminum Third Rail, 04 (Four) kilometres stretch between Shyambazar and Central station of the DOWN line.

This highly conductive Aluminum Third Rail is capable of reducing the system voltage drops and subsequent energy losses, because of its superior electrical conductivity. This less voltage drop in the third rail will help to achieve faster acceleration on the track, catapulting an improvement in the efficacy of Metro operations. In this new system a huge amount of energy will be saved which will in turn help the Metro Railway to reduce its operational cost. As a result, the entire expenses for replacing this third rail could be realized within three years by saving this operational cost.

Apart from this, Aluminum Third Rail will require less maintenance and will be highly reliable and stable. In a hot and humid city like Kolkata, this replacement will be very much beneficial, since lesser heat will be generated inside the tunnel during the time of contact of Third Rail Current Collector (TRCC) with this Third Rail. For maintenance work the New Third Rail will not require any welding as two such rails can be joined with the help of splice joint. It will help to maintain the air quality inside the tunnels. The work of replacement in the underground section has been targeted for completion within August, 2025.
