The private railway line of Sagar Cements being laid with an investment of Rs 120 crore is expected to be commercially operational next month. The full commercial operations will begin after safety checks by end of July, according to the company. The seven-km line, which is expected to improve Sagar?s market reach and cut freight costs, will connect the company?s plant near Matampally in Nalgonda district of Andhra Pradesh, with the main railway line.The savings will be in the form of cheaper inward and outward freight.
