In the recent past, the expansion and innovation in an engineering domain is growing trend. Some people believe that it is required to upgrade the existing railway infrastructure, so that it is ready to incorporate the technology of fast trains, whereas, there is a section of people who think that the same funds should be utilized to provide more security and reliability with existing railway lines. In my opinion, it is important to maintain the balance between both approaches, as the evolution of new technology is not a blocker for enhancement of the existing system.
