Test track

A test track assembly comprising:

• a test track the test track comprising a support structure and at least one track portion-adapted for testing a spatial structure;
• the test track assembly comprising at least two different interchangeable track sections, each of the at least two interchangeable track sections comprising an action track portion, each of the action track portions comprising a different geometrical track path, the action track portions adapted to provide geometric challenges to a user who tests a spatial structure on the test track;
• wherein the support structure comprises a void adapted to accommodate one of the at least two interchangeable track sections in position, such that the action track portion is arranged adjacent to, and in continuation to the at least one track portion, the track portions comprising a starting point and the action track portion comprising an ending point, which are positioned opposed each end of the test track;
• wherein the test track assembly comprises a toy construction system, the toy construction system comprising several toy construction elements, wherein the toy construction elements each comprises one or more coupling organs adapted to be interconnected to form a spatial structure, said spatial structure adapted to be tested on said test track;
• and
• wherein the support structure is adapted to surround the test track, said support structure comprising a first end wall and a second end wall, and wherein the track portions extend consecutively in the longitudinal direction from said first end wall towards said second end wall, and the at least one track portion is sloping from the first end wall downwards towards the second end wall.
