About Vande Bharat Trains:

• Vande Bharat is an indigenous semi-high speed train, with maximum speed of 160 kmph. Currently, two Vande Bharat trains are in operation, with routes New Delhi-Varanasi and New Delhi-Katra.
• They are self-propelled trains that do not require an engine. This feature is called a distributed traction power system.
• It means Vande Bharat rake has eight motorised coaches, compared to a 16-coach Shatabdi type train with one source of power at one end of the train in the form of a train locomotive.
• It allows the train higher acceleration and deceleration as compared to locomotive-based trains that take more time to attain top speed or gradually come to a halt.
• It also has an intelligent braking system with power regeneration for better energy efficiency.
• New features in 400 Vande Bharat Trains: according to the budget, the 400 new trains are expected to be more efficient, with superior aerodynamic profile.
• These trainsets will be built with aluminum instead of steel. An aluminum body will make each train set around 40-80 tonnes lighter than a current Vande Bharat. This will mean lower consumption of energy as well as better speed potential.
