As part of the Make in India initiative, these all-weather transformers were to be produced in Vadodara, Gujarat.In 2017, Alstom outsourced the task of developing, testing, and maintaining the brakes of the locomotives to German brake manufacturing firm Knorr-Bremse. Also a part of the Make in India initiative, these brakes were to be produced at Palwal in the Indian state of Haryana.The couplers of the locomotive were designed and developed by French Railway company Faiveley Transport. Around 85-90% of the components will be procured from within India.The first body shell of the locomotive was... more... |
