I’ve been on trains before this. There was the Tokyo system, I’ve ridden subway systems, and there was the Bell Tree Express, but that was a special event.

[Notably, ‘subway systems’ in this case is a euphemism for the London Tube system, since Masumi is trying her hardest to pretend she has no British ties.

Despite that, she has ridden normal trains before this so she takes a drink of her juice.]
