The Hitachi small-type monorail is a straddle-type monorail built by Hitachi Rail for the use on the Sentosa Express. These trains are part of Hitachi Monorail line of ALWEG-based monorail. The trains were part of a project to replace Sentosa's previous aging monorail system. The trains are fully air-conditioned.
Design[edit]
Each train set has its own exterior colour scheme – green, orange, blue, purple, pink, yellow and red. All trains are for passenger service, except for the maintenance train.
The interior of the trains consist of colours green and orange. These cars have foldable seats that can make room for more standing space during periods of high usage. Passenger Information Display Systems in the form of LED Displays are installed above each door in all passenger service trains to supply route information. Each car has two wheelchair bays.
Operations and safety systems[edit]
Trains and platform screen doors were previously manually operated by train attendants; the trains utilised digital automatic train protection (ATP) to ensure trains keep a safe distance between each other and automatic train supervision (ATS) to provide the route setting for the train to travel.
With the upgrading to the wireless communications-based train control (CBTC) system in 2017, trains and platform screen doors are now operated automatically.
Trains cruise at 15 to 50 km/h (9.3 to 31.1 mph) but is designed to speed up to 80 km/h (50 mph).
Refurbishment and upgrades[edit]
The Vacuum Fluorescent Display (VFD) has been changed to a newer updated LED Displays with route information.
A signalling system upgrade was also upgraded to Communications-Based Train Control (CBTC). With the change in Signalling System, it allowed more trains to run on the network.[1]
