Description from original author:
This is not a a replacement or addition for LEGO Duplo Train-Tracks. It just so happens that my kid confuses the different toys and uses them side by side. But kids are kids :D
The track element is split into 6 interconnected segments which allows for a complete different type of track with lesser constraints then a duplo train track. As it is not an elastic design, there is no tension to the rest of the track. But the train may move the segments when it is driving over the track.
