From the Super Mario Wiki
The Train Station is a place in Mario Party Advance. It is located in the Town Area of Shroom City. It is filled with smoke, which makes everything difficult to see. A single black train is docked in the background, and large, sturdy arches are suspended over the entire station. The single train is the only one currently operating, and an employee at the Train Station, Shy Guy, is in charge of taking care of it. At some point, the train runs out of Coal, leading to Shy Guy asking the player for help and starting the Locomotionless quest. As Shy Guy is unable to leave his post at the station, he asks the player to pick up some coal at the nearby Vending Machines. Once the player brings some coal to Shy Guy, he is able to start up the train again and rewards the player with the Cake Maker Gaddget.
