We were constructing a railway line for the next hundred years. So we planned it as a modern line, a high-speed route. We decided to have at least a minimal speed potential of 160km per hour. I said, the line itself should be capable of carrying trains at 160km per hour. In those days, there were no engines or coaches, which could run at that speed. But the country would definitely progress and the day would come when we would manufacture high-speed engines and high-speed coaches. So, the lines should be planned and constructed for a minimum speed of 160km. This was the first decision we took.
