The National Stock Exchange (NSE) has tied up with the Railways for a unique investor education programme. Three Rajdhani expresses are to be renamed NSE Rajdhani Express, all the coaches will be plastered with messages from the NSE — don’t give your broker your password, and messages like that — and the Railways are to be paid Rs 33 lakh per year per train. The amount will be raised by 10 per cent the first year, 15 per cent the second year, 20 per cent the third year and then 25 per cent. More trains may also be taken up later. The Railways have done similar deals in the past with Airtel and Kerala Tourism but this is the longest-duration contract. The first such Rajdhani will be flagged off today at New Delhi’s Nizamuddin Station.
