ElI5: Why do subway trains have a flat front rather than being streamlined?
In: Other
The train occupies most of the tube. That means that pushing away the air with streamlining won’t work. There is a concrete wall there.
Streamlining is great for high-speed trains that run out in the open countryside, but once you get in a tube that you mostly fill, all shapes are essentially flat. At that point, save some metal and just make the end flat.
