The number of passengers might change a bit (some might opt out because they don't like the new idea... but some more (women especially) might opt-in feeling safer?
So... overall, I assume the number of passengers probably wouldn't change that much.
And the number of carriages would stay close to the same - after all, all we're changing is distribution of passengers.
So... even if the number of passengers DID go up... the number of carriages would expand in proportion. And the same if the number dropped.
So I don't get why you assume increased prices for everyone.
