What they give is the ablity to build very smooth curves and long 2:3 ratio straights. The 90 degree turn would have the radius of 15 current straight units. Also two 2x6 curve parts could provide a switch to a parallel track with one unit next to the current one instead of 2 units gap in vanilla game. Similar effect could be achieved with 72 degree parallel tracks. Well, only three new pieces could provide a massive amount of new combinations and layouts.
What do you think?

*1 unit equals 2 in game squares.
