Y junction main line new
Y junctions is also become much smaller. You will be able to save 80 studs in length, 32 studs in perpendicular direction. Even the the new double line junction is 16 studs smaller in length then the existing single line one, and it is 16 studs bigger in perpendicular direction.
Please support. The bigger support, the greater variability.
I am open for any suggestions. If you see any mistake, or if you have any question comment, please.
