Just past the station is the service area. Every 3 to 5 runs the train needs to be removed to have the undercarriage (and occasionally the passengers) tightened down. There is no glue in any of this roller coaster, and the forces are extreme. At this service area there are two sets of tracks which slide side to side. You can service one train while another is running, and then slide the track over to take out the old train and put in the new. Back and forth action is controlled by the motor in the back of the picture. The motor in the foreground controls 4 axles with tires attached to stop the train or move it forward or backwards. For lack of 9V polarity switches, this motor and the motor controlling the station wheels are on the same switch. In the background is the base of the roller coaster's loop.
