Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

China amazed me twice recently, first extracting the e coli strain of the German food poisoning, and this. They may be marching beyond what other do not want to give credit to.

I will become a patissier, God willing.

Regarding giving credit, there is a story to tell that I didn't want to cram into the diary.

The domestic rail industry was mostly perfecting transferred technology. This included hybridisation: in particular, the Velaro nose support structure (which keeps the nose rigid against wind pressure) replaced the lighter Shinkansen structure in the CRH380A. Meanwhile, some key parts (like motors, power electronics, gears, pantographs) were still supplied from abroad. However, the new trains were presented with nationalistic propaganda, to the extent that sometimes the foreign suppliers weren't mentioned at all.

In particular, there was a row between China and Siemens when a contract for CRH380B trains was announced the the former as one for two Chinese companies exclusively, while Siemens revealed itself as third contractor, and the Chinese media got wind of it. Siemens also insisted that it never transferred the technology for some core components (hence the new version, the CRH380C, with Hitachi electronics).

Meanwhile, however, in a rail technology journal article describing the Velaro D (which I compared to its CRH380B step-sister in the diary), Siemens says that some of the aerodynamic improvements were "tested on Velaros in China". Now, the Velaro D's front design, windshield, support structure, roof extensions, and the spoiler below the nose ('cowcatcher') are new developments that can't just be applied to an existing train, and the underframe shroud cutouts for the bogies are necessarily different due to the narrower cross-section. The remaining possiblitires are: the diaphrams between the cars, the bottom of the train, and perhaps the pantograph wells (the 'holes' in the raised roofs into which the pantographs are lowered).

Then, the question is: who originated these designs (which are present in both the CRH380B and the Velaro D), Siemens or its Chinese partners? It may well be that Siemens practised some reverse technology transfer.
