*Project Synopsis*: Goods train brake vans in Indian Railways lack basic facilities like lighting and fans, forcing guards to work in darkness and discomfort. This project introduces a simple, sustainable system that generates electricity through a dynamo connected to the train’s wheels. The energy powers lights, a fan, and charging ports, ensuring better working conditions for guards.

*Problem Narration*: Goods train guards face severe challenges while monitoring train movements at night. The brake van lacks lighting and ventilation, especially when the train halts far from stations. During stops, there is no airflow or visibility, making it difficult for guards to record train data safely. A self-sufficient system was needed to provide light and fan power.

*Solution Description*: The project uses a dynamo-based energy generation system to power lights and fans in goods train brake vans. A small dynamo motor is connected to the van’s wheel through a gear mechanism. As the train moves, the wheel’s rotation drives the dynamo, converting mechanical energy into electrical energy through electromagnetic induction. This energy is stored in a battery for later use. When the train halts, the stored power supplies electricity to LED lights, a fan, and USB charging ports via switches. A diode ensures unidirectional current flow, protecting the system, while a USB charging module regulates output voltage. The setup is built using simple materials—cardboard, switches, a dynamo motor, a diode, LED bulbs, a fan, and a battery—to create a working model. This innovative, eco-friendly design offers a reliable and cost-effective solution to improve the working environment for railway guards.

*Solution Marketability*: The system is cost-effective, requiring only ₹800–₹1,000 for materials. It produces free, renewable electricity through motion, reducing energy dependency. The model can be easily replicated across goods trains to improve guard safety and comfort. Its simplicity, low maintenance, and sustainable design make it a practical solution for Indian Railways’ brake vans nationwide.
