Shunting with buildings in place

Minimum Radius Test

I was wondering what the minimum radius my O-16.5 rolling stock would run on was, so set up this little test with a bit of flexitrack on the dining room table. The radius is about 185mm to the track centreline, tight enough to fit a semicircle on a sheet of A3 paper. At radii this tight, there is a fine balance between the distance from the axle to the coupling face, which must be kept as small as possible to minimise how far the coupling swings out, and the distance from the end of the chassis to the coupling face, which must be maximised to prevent wagons touching and pushing each other off the track as they turn the corner.

Shunting Testing

A first test of the magnetic couplings for hands-free shunting.
