Oh, I missed it. But you guys already linked my 2 cents about it.
Had a good laugh at Peter34's comment, also, no it's totally not silly, you're silly.
Id love to see more feedbeck on the question DerivePi raised: Which geometry is preferable,
the new flexible one, (

or the fixed old one? (

(both already linked before)
Also the deconstruction issue gave me an idea for rail building:
As always, there should only be one generic rail piece in the inventory. You can build it as a straight piece (rotate as usual), but shadows of the curves appear, which might be build in it's stead, like so:

This only happens, when you build connecting to prexisting rail. These shadows do not invoke the construction bots. They disappear, when you deselect the rail or build another rail piece. The curves are actually built, when you click on them, or when you build a rail piece connecting with them. In this case, the straigt disappears again, if it is terminal. If it is connected on both ends, it stays where it is. You may build on an existing continuous rail to display the shadows of the 4 curves (left and right, both directions) which can be built there to branch the rail.
Actually building a curve costs 4 rail pieces (same as current price, mathes it's length). Since one piece is already spent for the straight which will be replaced once the curve is built in it's stead, the remaining cost of 3 pieces is taken out of the inventory when the curve is actually built. Full cost of 4 in case of a branch.
I think this way, new players can easily see how to build curves, and it's seems to me an elegant way to build advanced stuff also. It is however a new variant of the build action not used (usable) anywhere else. But it expands very well to two different radii as used in the proposed new rail geometry.
