🚆 𝗧𝗿𝗮𝗶𝗻𝘀 𝗣𝗿𝗼𝗽𝘂𝗹𝘀𝗶𝗼𝗻 𝗦𝘆𝘀𝘁𝗲𝗺 🚆 A Propulsion System is the technology that moves our metros and trains, converting electrical energy into motion, enabling high-speed, efficient, and environmentally friendly travel. 👇𝙃𝙤𝙬 𝙞𝙩 𝙬𝙤𝙧𝙠𝙨: ⚡ 𝗣𝗼𝘄𝗲𝗿 𝗖𝗼𝗹𝗹𝗲𝗰𝘁𝗶𝗼𝗻 Electricity is collected from the grid via Pantographs (for overhead wires) or Third-Rail Shoes (for third-rail systems). 🔄 𝗣𝗼𝘄𝗲𝗿 𝗖𝗼𝗻𝘃𝗲𝗿𝘀𝗶𝗼𝗻 (𝗖𝗼𝗻𝘃𝗲𝗿𝘁𝗲𝗿/𝗥𝗲𝗰𝘁𝗶𝗳𝗶𝗲𝗿) If the system uses AC, it’s converted to DC (in DC-powered networks). In AC networks, a rectifier adjusts voltage and frequency to match the train’s motors. 🌀 𝗜𝗻𝘃𝗲𝗿𝘁𝗲𝗿 Converts the DC back to AC to power AC Traction Motors, ensuring smooth and precise control over speed and acceleration. 🚂 𝗧𝗿𝗮𝗰𝘁𝗶𝗼𝗻 𝗠𝗼𝘁𝗼𝗿𝘀 The heart of the system! The AC Traction Motors transform electrical energy into mechanical motion, propelling the train forward. 🧠 𝗧𝗿𝗮𝗰𝘁𝗶𝗼𝗻 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 𝗦𝘆𝘀𝘁𝗲𝗺 Monitors and adjusts the motor performance, controlling acceleration, speed, and ensuring efficiency. It manages power flow to optimize energy use. ⚙️ 𝗚𝗲𝗮𝗿𝗯𝗼𝘅 & 𝗗𝗿𝗶𝘃𝗲 𝗠𝗲𝗰𝗵𝗮𝗻𝗶𝘀𝗺 Transmits the rotational motion from the motor to the train’s wheels through a gearbox, turning electrical energy into mechanical movement on the tracks. 🛑 𝗕𝗿𝗮𝗸𝗶𝗻𝗴 𝗦𝘆𝘀𝘁𝗲𝗺 Regenerative Brakes slow the train down by converting excess kinetic energy back into electrical energy, which can be fed back into the grid or stored for later use. 🔋 𝗔𝘂𝘅𝗶𝗹𝗶𝗮𝗿𝘆 𝗣𝗼𝘄𝗲𝗿 Powers non-traction systems like lighting, HVAC, and onboard electronics using a separate supply system or energy from the braking process. 🔒 𝗠𝗼𝗻𝗶𝘁𝗼𝗿𝗶𝗻𝗴 & 𝗦𝗮𝗳𝗲𝘁𝘆 Continuous real-time monitoring ensures smooth operations, balancing power, speed, and braking for safe and efficient journeys.
