This is a game that needs no table. So you could play it on a train, in a plane or even in the back seat of the family car on a road trip.
Players hold a hand of tiles as though playing cards, but have a score bag hanging on a loop from their wrist.
On a turn, a player will draw a random tile from a draw bag (the railway yard) that gets passed around after each turn. The draw bag holds rolling stock (locomotives and wagons) and loads.
Then the player discards a tile from their hand. That tile may go into their own score bag or back to the yard to get them an action.
What players are trying to do with the score bag is create a loaded train, pulled by the correct locomotive type, worth the most points when the game ends.
