A micro-expansion for 1830: Railways & Robber Barons featuring one city, Chattanooga. It is in honour of Mark Derrick's Chattanooga Railgaming Challenge, held every year in Chattanooga.

This expansion adds one city to a less congested corner of the map, giving the players an incentive to build into otherwise quite empty area.

This was a give-away item with purchase in Spiel '11.
