I am not familiar with the set but I know that with the Lost and Found flip face Hiro 2 double button short tracks came with it. Each short track has a button on each side. Maybe you need another track like this one to place in the opposite direction on the layout to change the face back. I beleive I have also seen curved tracks with flip face buttons. http://www.ebay.com/itm/Trackmaster-FLIP...4ae9ae11b7
