Railway Minister Piyush Goyal on Thursday emphasised on the need to use technological innovations to make the railways safer and more efficient while expanding its capacity at the least cost. "Unless we evolve with technology and with time, an organisation cannot survive," Goyal said after inaugurating the two-day International Conference on Technological Advancements in Railways and Metros here.

"There are very simple interventions like the concept of a freight convoy that does not require the latest technology but just a little simple thinking that can improve efficiency," he pointed out.
