BENTONG: The two tunnel boring machines (TBMs), which will excavate the twin-bore Genting Tunnel portion of the East Coast Rail Link (ECRL), are the largest of their kind in South-East Asia, says Transport Minister Datuk Seri Dr Wee Ka Siong.
With a cutter head diameter of 8.98m, the entire TBM will be 266m long when fully assembled and will weigh in at 1,600 tonnes, making them the largest ever put to work in South-East Asia, said Dr Wee after he visited the Genting tunnel portion here yesterday.
