new tracks
Tokyo, 2010.07.23
The new track pieces that I picked up have revolutionized our train layouts.
Who'd have thought that a male-to-male or female-to-female adapter could be so effective. But they've enabled so many new possibilities. Take, for example, this simple loop.

a simple rial loop
This is impossible without the male-to-male connector. Note, also, the female-to-female connector that joins the loop to the main line—freedom from abandoning your plans because the parts don't fit!
The improved versatility of the system really makes me wonder why Brio didn't ship these adaptors with the set we bought!
