The system will incorporate lessons learned in the construction and operation of the Docklands Light Railway in such areas as noise reduction and insulation, which will be particularly appreciated in some of the more densely populated areas along which the system is to run. A tight minimum curve radius of only 38 metres offered by the trains means that the alignment of tunnel sections can be planned as far as possible to avoid major underground obstacles and other installations. The trains will be a close relation to the automatic trains supplied for London's Docklands Light Railway. Each vehicle is made of welded steel, designed to provide maximum protection against corrosion. Each unit has two motorised bogies and a third, articulated trailer bogie.
Suspension is rubber and air-sprung, and each unit is fitted with disc brakes.
Power units are supplied by Loughborough, England-based Brush Traction. A pair of 140 kW motors power two dc chopper control units, and regenerative brakes. Each twin-vehicle unit weighs 36 tonnes, and has 70 seats. Maximum capacity, at a ratio of six standing passengers per square metre, is 284 passengers. While each train has a fully-equipped driving cab at each end, these are only used in emergencies.
