And that word is, IMPRESSIVE. I mean, damn, China. You have really figured out trains.
The metros in Shanghai, Hangzhou and Beijing - all have signs with incredibly intuitive symbology, easy to navigate stations and maps, and bi-lingual in English. I think of signage in San Diego, and we don't even do this in Spanish. Shame on us, because it makes being a visitor so, so easy and enjoyable.
The high speed trains. I mean seriously, holy hell. Our train from Huangshan to Beijing tipped 300 km/hour (186 miles/hr) and in just about 5 hours it transported us the distance between Burlington, Vermont, and Chicago, Illinois. Plus, they are are so sleek and pristinely clean and pretty, just like the futuristic train stations.
