MRT trains have evolved over the years from being driven by an operator and having no visual passenger information systems, to being entirely automated with dynamic in-train route display. There are 198 train sets for the North-South and East-West Lines, but not all of them are made equally. The first and third generations of trains were made in Kobe, Japan by Kawasaki Heavy Industries; the second generation was constructed in Vienna, Austria by Siemens; the fourth and fifth generations were built in China by CSR Qingdao Sifang. They sport different designs and material, for instance, the oldest set from Japan has an aluminium finish whereas the Austrian set boasts a scratch-resistant acrylic finish. Some of the trains on the North-East Line and Circle Line are made in France by Alstom, whereas others along the same routes are made in Shanghai.
