Indian Railways is the world's second largest railway system that carries over 18 million passengers daily. Freight revenue makes up 62% of Indian Railways' income. Commercialization of Indian Railways aims to generate more revenue through transportation of both passengers and goods, introduction of information technology, and outsourcing of services like catering and parcel management. Key strategies for commercialization include reviewing value-adding businesses, reducing wagon turnaround times, and developing new products and services.
