Modelling in 5.5mm/ft using Z gauge to represent 15in or 40cm gauge

For a challenge to build a small diorama which would fit in a standard cakebox, I went a step further and built a working layout using an oval of Z gauge track a small working loco, and wagons modified from RocoHOe ones.

it is powered by a small battery, and is easily transported!

Figures are from 28mm wargaming suppliers, the car is I believe Corgi, and the building is converted from a Bachmann Underground Ernie model.

The loco body is a 3d printed one from Tom Bell, and the spiral staircase s one of my own 3D print designs.

The track and loco chassis are from Rokuhan .
