Group 1: Project Overview - The ECRL project spans a total length of 665 kilometers and is considered a "land bridge" connecting important towns on Malaysia's east coast with the economic center on the west coast [3]. - The Genting Tunnel, measuring 16.39 kilometers, is the longest railway tunnel in Malaysia and is designed with two parallel single-track tunnels [3]. Group 2: Construction Techniques and Achievements - The construction utilized both Tunnel Boring Machine (TBM) and drill-and-blast methods to minimize environmental impact during the excavation process [3]. - The project has set two national records in Malaysia for being the longest railway tunnel and the highest covered railway tunnel, located over 750 meters beneath the mountain [3]. Group 3: Challenges Overcome - The construction team successfully addressed several world-class challenges, including high ground stress, high temperatures, high water pressure, and long-distance ventilation [3]. Group 4: Economic Impact - Upon completion, the ECRL project is expected to inject new momentum into the balanced economic development of Malaysia by establishing a major railway transport corridor across the peninsula [3].
