NORTH OF CHANGSHA, HUNAN — Now I’m on the bullet train between Changsha and Wuhan, the provincial capitals of Hunan and Hubei, respectively.

We are zipping through the countryside at least at 100 mph. (There’s no display reporting our speed.) it’s quieter than an airliner — you can hear the air conditioner fans — but you know you’re on a train. The occasional clickety-clack noise gives it away.

This is not a bullet train like the one in Tianjin I rode in May. This one (train D150) uses similar rolling stock, but runs on existing and upgraded trackage. Top speed is about 250 km/hr (155 mph).

We left Changsha at 7:30 and arrive at Wuhan about 10:30. Very quick and relaxing.
