Just to name one example of this, in Bangkok the BTS Skytrain[0] is expanding pretty fast, and even though it's expensive to ride it's the only way around the awful traffic if you work downtown, ergo it's packed during commute hours. (There's an underground too, which is also expanding, but it doesn't go as far out.)
High-rise apartment complexes go up pretty fast too, when a new station gets built. Coming from the West, it's fascinating to watch: an area that would normally be somewhat insular, suddenly becomes a viable bedroom community for people who work downtown, and then there's a rush to get in on the relatively cheap real estate, and night markets open up for your after-work entertainment, and so on. All within a couple years.
OTOH there's massive oversupply in these high-rise complexes, so I'm not sure about the business dynamic for the developers, other than the fact that a lot of money is still desperately seeking a parking space outside the PRC
