A night train is a public room in which some people must sleep and others must talk. Pretending one rule can govern both is how every journey becomes an argument between strangers. A quiet carriage is the admission that the argument is structural.
The objection is enforcement. Who decides what is quiet, and who is humiliated when they get it wrong. The answer, from railways that have tried it, is a coach that is labelled, optional and boring. People who need to speak move. People who need to sleep stop negotiating with a stranger at midnight.
What happens next
One coach is enough. A whole train of silence would be a fantasy and a burden on families. A single coach is a design choice about as radical as a seat that faces backward. It will annoy someone. It will let someone else arrive able to work.
The trial that several commuters have asked for is not a moral lesson. It is a month of one labelled coach and a count of how many people choose it. If they do not, the idea can go back in the drawer without a speech.
