President Ram Nath Kovind has exhorted probationers of different railway services to make meaningful changes both at their workplaces as well as in society at large when they called on him on Wednesday, December 10, at Rashtrapati Bhavan. The President told the probationary officers that since they have joined an institution that provides them a unique opportunity to serve the nation and millions of citizens each day, they should live a life of optimism and develop a sense of positivity. This will allow them to nurture a spirit of innovation and emerge as solution providers.
