Iron arteries running across the subcontinent, the Indian railways are vital to the country. There a narrow gauge line chuff-chuff-chuffs up a hillside; here a goods train draws millions of tonnes of goods across the country. Cities grow around the railways and towns fade into obscurity once the trains don't stop there any more. The Indian Railways is a little world; a microcosm of India; a way of life. And whether you're a rail enthusiast or a train traveller, a trainspotter or a just someone who wants to know which train to catch, we've compiled a whole list of railway sites you can check out.
