SENTOSA'S MONORAIL SYSTEM
The Sentosa Express is a monorail line that connects Sentosa island to the mainland via the Sentosa Station at VivoCity.
Built at a cost of $140 million, it is driver-operated, but most of its functions are fully computerised and highly automated.
Development started in June 2003 and was completed in December 2006, with two-carriage trains plying the Sentosa, Imbiah and Beach Stations.
The fourth station, Waterfront, opened in 2010.
In 2005, a year before the Sentosa Express went live, the 32-year-old Sentosa Monorail was dismantled.
When the Sentosa Monorail was introduced in 1982, the non-air conditioned trains were meant to be a gimmick, said then-chairman of Sentosa Development Corporation (SDC) Alan Choe.
But long queues started forming at the stations and it became difficult to source for spare parts for the old trains.
That was when SDC started looking at a new monorail system - today's Sentosa Express - to meet passengers' needs.
