Having lived and worked in China, this is my opinion. The Chinese are master copiers. They can take anything apart,  study it and put it back together again. So if they have the blueprints, etc, they can 'copy' trains.  But…when one rides the trains you can sense the difference in comfort and noise right away. The Bombardier trains were [are] more comfortable in seating , less noise of seats and less noise of tracks/wheels. When scheduling travel I would deliberately choose times the 'original' Bombardier trains were running in order to get a more comfortable ride. You wonder how one does that?--well when you work in these various countries around the world, you learn by observing and you just know what train you are on. Look at them closely as well. So many contracts may be going to Asia, but in future their seemingly cheaper contracts will cost the buyer more money on repairs, maintenance and parts anyway.
Nothing beats the Canadian Bombardier.
