Explanation:

The Hyperloop is a concept proposed by billionaire inventor Elon Musk, CEO the aerospace firm SpaceX.
Musk’s Hyperloop consists of two massive tubes. Pods carrying passengers would travel through the tubes at speeds topping out over 700 mph. For propulsion, magnetic accelerators will be planted along the length of the tube, propelling the pods forward.  The tubes would house a low pressure environment, surrounding the pod with a cushion of air that permits the pod to move safely at such high speeds, like a puck gliding over an air hockey table.
Musk’s design recommends an air compressor on the front of the pod that will move air from the front to the tail, keeping it aloft and preventing pressure building up due to air displacement.
A committee under NITI Aayog is formed to look into the feasibility of having hyper loop transportation, where a pod like vehicle is propelled through a near-vacuum tube connecting cities at high speeds matching that of aircraft — in the country. Govt of Maharashtra has signed up deal to set up hyperloop trains in the state.
