Indian Railways is widely regarded as the largest public sector undertaking (PSU) in India. Its distinction comes not just from its significant contribution to the economy but primarily from its vast operational network, which spans across the entire country, and its status as one of the world's largest employers (with over 1.2 million employees). It is the backbone of India's transport infrastructure, facilitating both passenger and freight movement on a massive scale. While other PSUs might lead in terms of revenue (like IOCL or ONGC) or market capitalization (like SBI), Indian Railways' sheer scale of operations and human resource base makes it the single largest public sector entity.
