Riverside Station is the only stop for the Excess Express on its way to Poshley Heights from Rogueport in Paper Mario: The Thousand-Year Door. It was named because of the river beside it which had dried up. When Mario arrived there looking for the Crystal star, The Drawbridge across the river was up. Mario entered the Station to find the Drawbridge switch. He found it and encountered strange enemies called Smorgs. These later snuck onto the Excess Express and abducted the passengers.
