I know that Philippine has already had electrified rail lines, which are owned by Manila metro.
But, track gauge of Manila metro lines is 1435mm, while exported electric multiple units had run on tracks whose gauge is 1087mm.
Furthermore,
According to the article on Wikipedia(Philippine National Railways#Future plans),
The Northrail project involved the upgrading of the present-day single track to an elevated dual-track system, converting the rail gauge from narrow gauge to standard gauge,
If this plan were to be carried out, exported electric multiple units could run only on South Main Line.
I would like to know the facts.
