- Reading: Metro train with plug door
Are the D000 trains on Seoul's Shinbundang Line the only ones?
It operates like a regular subway line, but the train will travel at 90km/h (in operation, not just test) in some parts of the track, requiring the plug doors usually used on high-speed passenger trains.
Plug doors are more or less an aesthetic choice, makes building things easier when you have windows very close by. Speed is pretty much never a factor
The Siemens Nexas is all plug door for example just for shits and giggles. On the other hand, Tokyo's subway trains (among others around the world) lack plug doors and run at over 100km/h with no fucks given. You will also note that on some sets like the 15000, they opted for a windowed slot instead of plug doors (not unlike some Japanese suburban trains), partly because it's harder to push people into a train with plug doors though an arguably ugly solution
this is a really good discussion, I hope everyone on the board becomes involved in this discussion

225km/h, no plug doors.
Pneumatic-powered sliding plug door for Amtrak's ACELA high-speed trains.

>Siemens Nexas
Aren't those technically commuter trains?

MoMo, Nexas, close enough. It does run U-Bahn in Europe. Though I guess I should've clarified
I'll plug your door, anon.

Ahhh but you see these doors engage a pressure seal when the train reaches about 15 mph, locking them shut.
