Class 143 in Karlsruhe.
During the years Germany was divided, the two nations’ locomotives developed in different ways: the west bought locos from the Likes of Siemens and Krupp, whereas the DDR (East Germany) was supplied by centralised locomotive works in Eastern Europe whose policy seemed to be that styling was for the Western Imperialists. In some cases it seems that locos able to start, stop, or pull the skin off a rice pudding were considered suspect as well, judging by some of the less successful clunkers that were built.
The class 143 above was an east German design that was successful enough that the first locomotives built by after reunification were of this type. Apparently the cab is supposed to be aerodynamic. I can’t say that’s how I’d describe it.
