IR is now embarking on a plan for enhancing its technology , with possible restructuring of the R&D functions. The core idea stems from Dr VK Saraswat , a Member of the influential government think tank , the Niti Aayog . We lead this issue with an exclusive chat with Dr Sarswat , that provides a preview of the likely shape of cahnegs. Of interest also is the rail history book co-authored by Bibek Debroy, also a Member of the Niti Aayog. Th technology reports cover digitization led efforts in railways , including on possible forays of AI. That is why we call this issue as one of ’the many hues of railways’.
