my toy train track

Wanted more tracks for my toy train so I designed some.
s gauge, I think, ~24mm
Planned to use 2g micro servo for switching.
There is also some Arduino and Android code on https://github.com/bond4u/LocOp
Control Your Loco from Android app over Bluetooth.

Added some .stl files.
In scad You can specify length,radius,arc:
straight(150);//150mm straight piece
curveR(500,22.5);//curve right with 500mm radius and 22.5degrees arc
switch1(500,30);//switch to left and right with 500mm radius and 30degrees arc
