One of my dinner guests last night is from China. She'd just returned from a trip back home after two years in Canada. She flew into Shanghai & was pleasantly surprised when her mother met her at the airport. Seems her parents now live only an hour and a half from Shanghai by rail, although it's still a 500 K distance.
The new Semi-High Speed line, not one of the very fast maglev super trains, but still, station to station in 1.5 hours, allows her parents to go for lunch in Shanghai, then return in plenty of time for dinner.
What surprised her was that her parents hadn't thought to mentioned the new service. An indication of how rapidly things are changing in some parts of the world.
