Dubaï “The Hesop system at the heart of Dubai’s 2020 road project”

Thi Mai Tran – Managing Director Gulf States – Alstom

Can you us give more details on Alstom’s involvement in the Dubai metro line extension for Expo 2020?

The particular challenge of the 2020 road project lies in its operational complexity. Four factors must be taken into account: integrating the extension with the existing metro line, keeping the current rolling stock working, maintaining the current network running and the extremely tight deadline – knowing that the delivery of the project was planned in spring 2020 to coincide with the opening of the World Expo in October 2020. Alstom will bring its expertise in implementing integrated systems.

In what way is it innovative and energy efficient?

Alstom will fit the line with the innovative Hesop system, which can convert 99% of the energy lost by the trains during braking and pump it back into the power grid.

What are the other recent, current or future projects for Alstom in the UAE?

Alstom delivered phase 1 of the Dubai tramway in 2014. Phase 1 involved the supply of 11 Citadis trains, 11 km of catenary-free track, 11 stations and various other types of equipment (electrification, signalling, ticketing etc.). The Dubai Tram is the first tramway in the Gulf equipped with APS technology (ground-based electric supply system). The tram and its systems have been 100% tropicalised to cope with the extreme heat and humidity. Alstom has maintained the Al Sufouh tram system in Dubai for the last 13 years.

What does this contract include?

It includes routine maintenance (preventive and corrective), equipment renewal, technical support, spare parts inventory management and major maintenance. It also covers station maintenance, the maintenance depot, tracks and platforms, switches, power supply and distribution facilities, the APS and communication systems as well as signalling and other electromechanical installations.
