THE 2012-13 railway budget, presented by railway minister Mr Dinesh Trivedi in the Indian parliament today, calls for total spending of Rs 601bn ($US 12.3bn), which Trivedi says is the highest ever. But capital investment during the 12th five-year plan, which runs from this year to 2017, will more than treble from Rs 1.92 trillion during the 11th five-year plan to Rs 7.35 trillion.
