Hitachi Small-Type Monorail (Sentosa Express)

The Hitachi Small-Type Monorail (Sentosa Express) trains are the first to use Hitachi's small- and straddle-type monorail in Singapore. The straddle-type small monorail system was developed by Hitachi in Japan as a small, standard and cost-effective solution to the transportation needs of small to medium-sized cities.

Some other features of the straddle-typed small monorail include being small in size, light and producing low noise levels; the capability of a greater passenger carrying capacity; a slim guide way structure as well as lower construction costs.

There are 7 trains of two cars each operating on the 4-station Sentosa Express, which opened on 15 January 2007.

These trains replace the 23-year-old Sentosa Monorail system that closed in March 2005.

History

The Sentosa Express was built to replace the 23-year-old Sentosa Monorail that closed on 16 March 2005.

To cope with the increasing ridership on the Sentosa Express, 2 additional trains were added into the system on 1 December 2009, on top of the existing 4 trains.

Signalling System Upgrade

The contract to enhance the capability of the Sentosa Express with a new wireless CBTC signalling system and another train set was awarded to Hitachi on 19 November 2014. The enhancement enables the line to cater to more passengers and better serve the increasing number of visitors entering Sentosa.

The new CBTC system uses wireless communication to transmit information on trains' positions and speeds so that the distance between trains can be reduced, yet safe and constant. This will significantly reduce the intervals between trains, cutting travel times for passengers, and allowing an addition of another train for greater capacity.

The new system also includes an Automatic Train Operation (ATO) function, allowing the trains to be fully automated. This relieves the train captains of manual train operation, allowing them to take on other tasks such as managing safety and security on the train.

With the upgrade, a row of seats from both ends of the train are replaced with a signalling box, housing the new signalling equipments.

Since November 2017, the Sentosa Express has switched over to the new signalling system and the additional train put into service on 24 November 2017.
