2. When the chairs are completely spread out, male passengers with a height of1.8m can also lie down and sleep comfortably. Business travelers also have free blankets, cushions, slippers, snacks and meals.
3. EMU generally refers to a rail vehicle that carries the operating load and has its own power; But in modern EMUs, EMUs are closer to the role of locomotives in traditional trains. Generally speaking, this kind of emu does not bear the running load. In China, trains with speeds of more than 200 and CRH Harmony are called "multiple units".
4. China's EMU trains are divided into three grades: high-speed EMU (speed 250 and above, symbol G, mainly corresponding to high-speed railway), and there is no upper limit of speed limit.
5. Ordinary EMUs or medium-speed EMUs (No.D, speed 160 and 200 kilometers, mainly corresponding to high-speed railways) and low-speed EMUs (CSR Qingdao Company delayed its technical capability and studied the speed 140 kilometers to adapt to urban light rail).
Extended data
1 and "Harmony" EMUs generally adopt AC drive and distributed power. The front of Harmony is streamlined to reduce air resistance. The running speed is more than 200 kilometers per hour, and the highest can reach 350 kilometers. "Harmony" train is controlled by computer, and its running data is displayed electronically.
2. The seats of Harmony train are divided into first-class seats and second-class seats. The first-class seat is arranged in 2+2 mode, and the second-class seat is arranged in 3+2 mode. The seat is adjustable, the direction of the seat can be turned 180 degrees, with a foldable coffee table. Automobile interior design pays attention to humanization.
3. Automatic temperature adjustment and air conditioning. All doors are electric plug doors. There are also some models that use sleepers on long-distance lines. 200-kilometer vehicles mainly run on existing lines, and 300-kilometer vehicles mainly run on high-speed dedicated lines.
