Kolkata Metro Switches To Aluminium Rails, Promises Faster Trains And Big Savings

The Kolkata Metro has replaced the steel third rail with an aluminium one at the Girish Park siding under the Dakshineswar-New Garia corridor. This switch aims to reduce energy losses by 84%, saving Rs 1 crore per year per kilometer. The new aluminium third rail has better electrical conductivity, which will lead to faster acceleration of the metro trains. The Metro Railway has set a two-year target to complete the installation of aluminium third rails across the entire network. Once completed, Kolkata’s Metro Railway will be on par with similar services worldwide.
