The first automated light rail service in Macau officially started carrying passengers on Tuesday, December 10, 2019, a little over a week before the former Portuguese colony marks 20 years since its handover to China. The Taipa section of the Macau Light Rail Transit (MLRT), or Metro Ligeiro de Macau (MLM), began operating nearly 17 years since it was first proposed in 2003, and cost some 10.2 billion Macau patacas (US$1.27 billion), nearly three times more than planned.
