Singapore has invested in mass rapid transport since the 1980s. The first train rolled off 1987 and today there are five lines, with more under planning. The recent line that was completed is known as the Downtown Line and was nothing short of an engineering feat. One spot in particular, had the tunnel of the DTL passing close by, or rather above the existing North East Line tunnel 1 meter. The continuation of this DTL tunnel elsewhere also crossed below the North-South and Circle lines, 8 and 3 meters respectively.
