Each player starts with a supply of 17 double-decker buses, two transportation cards in hand, and one or two destination tickets that show locations in London. On a turn, you either draw two transportation cards from the deck or the display of five face-up cards (or you take one face-up bus, which counts as all six colors in the game); or you claim a route on the board by discarding cards that match the color of the route being claimed (with any set of cards allowing you to claim a gray route); or you draw two destination tickets and keep at least one of them.
