June 27, 2024 a transportation system where an engine moves at a constant speed, and individual bogies (rail cars) can attach and detach from the engine while in motion. This system leverages the concept of relative velocity to make the process of boarding and alighting more efficient and seamless, even when the train is moving. Here’s a more detailed breakdown of the concept: 1. Constant Speed Engine : The engine moves at a constant speed without stopping. This ensures a steady and predictable travel time for the train. 2. Attaching and Detaching Bogies : Bogies (or rail cars) can attach to and detach from the moving engine. When a bogie needs to attach, it accelerates to match the engine's speed and then locks into place. Conversely, when a bogie needs to detach, it decelerates to a stop or slows down to a speed where passengers can safely board or alight. 3. Relative Velocity : Because...
