“By end of this year, we can start using the TR4. Mai-inaugurate po natin ’yan. Ang target natin diyan mga November, December start of operations of TR4. Ang usual travel time po natin diyan [para sa buong TR4] is four hours. Once mabuksan na po natin ang [buong] TR4 natin, magiging isang oras na lang po,” said the transportation secretary.

He then called the plan a “big ticket project,” further solidifying its importance. Construction for TR4 broke ground in March 2019, with initial operations expected to kick off in 2023.
