Yeah, like this other paragraph about a future announcement, one of the top 5 cities by population: they are all asian. Is it Tokyo? Only one of these that publishes GPS data for its transit system. Or is it "global" = US?
By the same token, getting real-time info out of all of these operators would seem a huge task...
But given the nature of Tokyo transport, it's hardly necessary in most cases anyway—everything runs extremely frequently, and pretty much exactly on time (so scheduled times are usually all you need), and the system's emphasis on rail over buses means that variability due to traffic conditions is rarely a concern.
