The rolling stock of Kolkata Metro Line 1 uses Indian gauge a broad gauge track which is manufactured by ICF, Chennai, and the electrical components are manufactured by NGEF, Bangalore. Initially, the rolling stock fleet was composed of 4-car rakes. Over the years there has been considerable expansion to the network, both underground and on elevated sections. With the increase in traffic, 8-car rake formation has become a standard for the Kolkata Metro. Presently there are 18 Non AC rakes and 13 AC rakes. Out of the 18 Non AC rakes, 11 will be phased out gradually since they have outlived their normal life of 25 years. The remaining 7 rakes are still in good condition so they will be refurbished and put into service in a phase manner. Until now, three types of trains have been used by Kolkata metro; these are - *BHEL Rake(1000 Series): 9 Rakes were manufactured by ICF, Chennai and were passed into service in the first phase when the metro initially ran from Esplanade to Bhawanipur (now Netaji Bhavan). These trains were dark green in colour and had a yellow stripe at the bottom. Later the colour was changed to white with a dark blue stripe. Presently they are yellow with a wide brown band at the bottom.The rakes are usually numbered from B1 to B9 but two of these have been condemned.
