The cutter head, the largest part of the first of six tunnel boring machines that will be used for the partial operability section of the Metro Manila subway from Valenzuela to North Avenue, has arrived in the country, signaling that work on the country’s first underground railway system may start soon.
The 74-ton cutter head would break, cut and grind rocks and soil by rotating its disc cutter. The tunnel boring machine, on the other hand, would be used to dig underground and lay out tunnels.
Other parts of the first tunnel boring machine, called Kaunlaran, are expected to be delivered within the month and will be assembled on the site of the planned 357-billion-peso subway.
Despite the challenges posed by the pandemic, Transportation Secretary Arthur Tugade still has his eyes set on the partial operability of the Metro Manila subway by December 2021 or February 2022 “at worst.”
