A group of probationers of Indian Railway Service of Engineers, Mechanical Engineers and Railway Protection Force called on the President Pranab Mukherjee at Rashtrapati Bhavan today. Speaking on the occasion, the President urged the probationers to always remember that through the services they were not merely earning their livelihood but were making a meaningful contribution to this great nation to which they belong. He said that they were getting a tremendous opportunity of serving the country and they must always show ingenuity, innovation and initiative while discharging their duties. <br/><br/>Mr. Mukherjee said the Indian Railways is not only one of the largest rail networks in the world but one of those which are well managed. He stated that Railways has a deeper meaning than being a mere transportation system. It integrates far-flung areas of the country. The President said like the Indian Post Office, it is one of the few organizations in the country which have a truly national character having influence over the whole country.
