A turn ends after a player have taken their 4 actions & moved the Passenger token.
After all Passenger movements are completed, new cards are drawn to replace those removed from the game so that there are again 4 Destination cards facing up.
The appropriate Destination token (Express / Standard) are then placed on the stations corresponding to the newly revealed cards.
The play passes to the next player in clockwise order (to the left), until the deck of Destination cards runs out.
