In order to support the economic growth along its east coast, Malaysia, in cooperation with China’s Belt and Road Initiative, is constructing a double track connection for passenger and freight trains.
This connection will significantly improve the connection to Malaysia’s East Coast Economic Region, enabling and supporting economic growth in the future. The line is expecting a ridership of 5.4 million by the year 2030.
Phase 1 of the East Coast Rail Link (ECRL) includes a 1’330 m long tunnel near Marang in the state of Terengganu for which Amberg Engineering performed the ventilation design.
Major challenges of this project included the identification of the most significant scenarios, as the planned passenger and freight trains create vastly different evacuation and fire scenarios. Both computational fluid dynamics and evacuation simulations were used in order to determine the effectiveness of the designed ventilation system.
Thanks to Amberg Engineering’s expertise a ventilation system could be designed offering a high standard of security for all reasonable emergency scenarios.
