It is only a test track.
More realistic trackwork can be used for the layouts. Someone mentioned here EW1 turnouts from Tillig - well, I'd suggest forget the EW1 and use EW3 instead (or at least EW2 if you don't have space for EW3) and don't forget to paint the sides of the rails rusty brown, it helps a lot.
Better (and more expensive) trackwork can be found at
http://www.ttfiligran.de/ Unfortunately only in German, but try to click through their www page.
They make the best trackwork I have ever seen in TT. They use Code60 rails (height 1.5 mm). Check their turnout EW 1855-1:8
