Even the mediocre VTA light rail in Silicon Valley has people standing during rush hour. although that is exacerbated by the California reluctance to sit right next to someone. Here when half the seats are sat in the rest of the people stand unless it is a big group like a field trip.
You can't complain about standing if there are still seats available though ...
Also, you don't see that here in NYC. People are gonna sit down if there's space available. Unless it's next to a crazy homeless person, but I've only ever experienced that on heavy rail, not commuter rail.
