New Delhi: The National Stock Exchange and the Indian Railways on Wednesday flagged off the Delhi-Chennai Rajdhani Express, with 17 decked-up coaches carrying NSE's message on investor awareness. The coaches, carrying the images of NSE's flagship index, the Nifty, will be used on two other routes - Delhi-Bangalore and Delhi-Trivandrum - at different times of the week. The stock exchange has tied up with the Railways to reach out to 2.5 lakh passengers expected to travel on the three Rajdhani Express trains this fiscal as part of their investor education campaign, reports PTI. "This is the first time that an exchange is conducting a mass outreach programme through the outdoor medium," said NSE Managing Director and Chief Executive Officer Ravi Narain. The three trains, running across the length of the country, stop at 34 locations in 11 states, Narain said, adding that it will help in reaching out to tier-2 and tier-3 towns. The campaign to spread awareness on crucial dos and don'ts with respect to online transactions and NSE traded products - with the motto 'soch kar, samajh kar, invest kar' (invest carefully) - will be extended to more long-distance trains, Narain added.
