Dice Tokens, Tunnels and Stations

You may hold at most 3 tokens of a type; starting your turn with 3 of a type, you can't take more of it that turn; you may discard tokens at the end of your turn. Tunnels: after claiming, roll the 3 Tunnel dice and add one more die or token per tunnel symbol, or your turn ends; you can't reroll Train dice after the Tunnel roll. Ferries need one die per Locomotive icon. A Station (Europe) takes 1, 2 or 3 Station dice for your first, second or third, and nothing else that turn.
