Your examples are regions covered pretty completely with substantial population (and therefore have electrical infrastructure throughout) implementing electrification in the small minority of areas that are remote for interoperability reasons. This is different than places like the Americas and sub-Saharan Africa where some main lines cross up to thousands of miles of mostly inadequate electrical-services areas. You basically have to build and service infrastructure exclusively for the trains in those cases.

Electrification can still be a goal in these places, but it’s not unreasonable for them to pursue hydrogen or even retain diesel while working on high-volume freight shuttle/passenger electrification. Please don’t do the thing everyone else does and assume I’m arguing against electrification - I’m just saying it’s not going to happen anytime soon in a lot of places for real reasons.
