Railways of Australia is a large 2-6 player map. This map has several unique features: a new terrain type - towns; region borders; and rebound Railroad Operations cards. When built, a town becomes a Gray New City on the map. There are also Railroad Operations cards that automatically build each of the 10 towns on the map. Players cannot build across region borders unless connecting through a city, or using a 'Triple Gauge' Railroad Operations card. This expansion includes junction track tiles for use with the Switch Tracks mini expansion. These new track tiles display the 2 lines coming together in each configuration. Switch tokens are also included so that players can use the Switch Track mini expansion right out of the box.
