TUNNELS

Tunnels are special Routes of somewhat unknown length.

When you attempt to claim a Tunnel, 3 cards are automatically drawn from the top of the Train cards pile.

For each card revealed whose color matches the color of the cards you played to claim the Tunnel, an additional card of the same color (or Locomotive) must now be played from your hand.

If you don't have enough cards of the proper color, your claim attempt fails: you keep your cards, but wasted a turn.

If you attempt to claim a Tunnel using Locomotives exclusively, you only have to play additional cards (which must then be Locomotives) if Locomotives show up among the 3 cards drawn for the Tunnel.
