A set of four metal trains, identical to the one used for The Transcontinental. (These extra trains are not used for playing The Transcontinental, they're a kickstarter bonus for train and board game component enthusiasts.
A set of four cloth bags to store wooden components for the game in player colours, with a drawstring tie, and embroidered with the Transcontinental logo.
3mm neoprene playmat with tile and card positions marked. Double-sided, with a colourful box-cover-image background on one side, and a more plain background with the thematic colour gradient on the other.
When using the play-mat you do not need to use the train board, but still require the track board.
