In the April of 2011, on 14-year-old student from Thailand was hit by a Mass Rapid Transit train in Singapore. She lost both her legs. According to one news report (Figure 3), the girl had fallen onto the tracks because "she had a dizzy spell while waiting on the platform". This incident took place at around 11 a.m. on a Monday, and the station where it happened was one where many people were expected to be waiting for the train at that time. One then wonders if it is possible for the girl to be walking around randomly (as a result of a dizzy spell) without being noticed. One could also examine how many steps such a random walker would take on the average before she fall off the platform?
