At the top of the display in the foreground is the Hysteresis Loop so called for its resemblance to a hysteresis graph. Below this is the Shuttle kit demo. These two displays are part of what is affectionately known as the Flower Stand. They are here placed on top of two self supporting cabinets, the nearer one demonstrates Super Block and RFID. The farther cabinet demonstrates the New DCC System and CBUS System.
