The Carrera GO!!! one of the most important accessories of the sets is the control connecting element, which connects the speed controllers and the power supply to the track. This is the central element, which also fulfills the start-finish function. After being built into the track, the control element operates the set accurately and precisely when used with the appropriate accessories and, of course, cars. There are three openings on the side, of which the two speed controllers can be connected to the outermost two (compatible only with speed controllers type 61663), and the power supply must be connected to the middle one. With the use of any specially built Carrera GO!!! a track or an existing set without a controller can be used.

Compatible with all Carrera GO!!! set from 2017, or only speed controllers type 61663/20061663 can be connected with this track element.
