@chinarailways: What shape are the wheels of a high-speed train? They may look cylindrical, but they're actually slightly cone-shaped. This clever design helps the wheelset naturally return toward the center of the track and smoothly negotiate curves, while the raised flange on the inner edge provides an extra safeguard. A small angle in the wheels makes a big difference on the rails. #ChinaRailway #RailwayABC #railway #train #fyp
