Yong | The Urbanist Singapore on Instagram: "Singapore’s first MRT trains, the Kawasaki Heavy Industries C151s, have now been fully retired.  Introduced in 1987, they were the pioneers of our rail system and carried generations of commuters for almost 40 years. With their final journeys last week, these trains move from daily life into history. #SingaporeMRT #C151 #UrbanHeritage #TheUrbanistSingapore"
