In 2006, Vandana Singhal made a small discovery while at a railway station in France. She noticed that the stone edging on the platform was rougher than the stone elsewhere. Passengers, she observed, were far less likely to slip as they stepped off the train.
At the time Ms Singhal was on a two-week training course at HEC School of Management in Paris. On returning to her job as a divisional railway manager for Indian Railways she adopted the French technique in Hyderabad. The idea was a success and was implemented across India.
