Can you take a 5 carriage while 4 carriage cards are still on the board?
The rulebook says you take the next highest carriage when the route is long enough, and two posters read it this way; one early objection was withdrawn.
Yes. The rules do not require the lower carriage to run out first. If you already hold a 4 and close a route of five or more cards, you take the 5 even though 4s remain.
