This was informed by Minister of State for Railways Kotla Jaya Surya Prakash Reddy in a written reply in Rajya Sabha.
In 2009-10, the railways incurred an import expenditure of Rs 1,303.46 crore, followed by Rs 1,353.17 crore the next year. In 2011-12, the import bill was Rs 1,288.64 crore.
On the estimated total expenditure on import in next three years, he said, it cannot be estimated "as railways resort to import in inescapable circumstances".
"Research Design and Standard Organisation/ Production Units are entrusted with the responsibility of developing indigenous sources. Owing to these efforts approximately 96 per cent of goods purchases on Indian Railways are indigenous," he said.
