I guess that means that you’ll have to have really precise parking and stopping, have pressure gates to connect to all of the entrances to the train and make sure to maintain each gate with more points of failure and depressurization. The logistics of parking properly (AI assistance would be nice). It could be faster to connect logistically, but definately more points of failure. Then again even if the pressure fails, the concequence is only wasted money. its still a functional mag lift train.
If I lived in a country where the government focused on the future like China does, I’d rather invest in biomedical research, sustainable agriculture, and researching the means to industrialize without harming the environment.
CASIC says the flatness of its test track is within an 0.3 mm (0.01 inch) tolerance, that the 6 m (20 ft) diameter vacuum tubes have a geometric size error less than 2 mm (0.1 in)
The tolerances for the tube itself in most parts is not the issue. The tolerances at the points most likely to leak are the real issue. I guess we’ll see.
You don’t have to re-pressurize the whole tunnel, just make a seal around the train doors.

Or an air lock system where the train pulls into it first then is re/de-pressurized depending on if it’s going into a station or leaving.
