Workers are set to start excavating the Philippines' first subway, using a boring machine brought from Japan.
The giant machine was unveiled at a ceremony on Sunday. It can drill up to 10 meters a day.
The 27-kilometer line will link northern Metro Manila with Ninoy Aquino International Airport. Journey time will be halved, to around 30 minutes. The project is aimed at reducing the capital's chronic traffic jams.
The project is part of outgoing President Rodrigo Duterte's program to boost the country's infrastructure development.
The Japan International Cooperation Agency is backing the project with a loan worth some 2.6 billion dollars.
Construction started three years ago, but was delayed due to the pandemic. The railway is now slated to be completed in 2028.
