No, but tell me about the trains in Canada or Australia or New Zealand instead. Curious what high speed, modern trains these nations have compared to China, or are they more backwards?
This is a silly comparison. How many cities can China connect with trains vs Australia's 7 cities spread over almost 4k km in both axes... It's not as much "backwards" as requirements are vastly different. Melbourne-Canberra-Sydney could be useful and is getting started now, but I wouldn't expect more for decades.
You have no idea what China being advanced compared to Australia has to do in a thread replying to someone claiming China is advanced compared to America?
Are you confused about threads? You're the first one saying China is more advanced here https://news.ycombinator.com/item?id=43981378 as an answer to "it doesn't make sense to compare train systems in those two countries". What is even the point you're trying to make here?
