Japan’s Transfer of Bullet Train Technology A Mistake. China, Of Course, Has Copied It
Odd, the Chinese never ordered any spare parts?
I know from personal experience how China operates. A team of Chinese engineers visited the outfit where I worked in late 1970’s, and paid good sum of money to buy all the engineering manuals and drawings of our product. Never bought a single product we manufactured.
Is this the same Chinese that can’t get the reverse engineering down by copying Russian made jet fighter engines?
No, the JP Bullet Trains run on regular rails.
This is the German Transrapid, which Germany was too cheap to deploy in-country.
