This is on the new fast train between Tianjin and Beijing. The old fast train used to take an hour. This one takes 28 minutes and hits top speeds near 340 km/hr. When the train gets up to top speed people get excited and start taking photos of the speed posted at the end of the carriage. I found their excitement contagious and took this shot of it. I superimposed the speed so that you could figure out why they were excited.
