NZR Motor Trolley 3.5" gauge
This is a simple model designed to represent an NZR motor trolley in 1:12 scale for 3.5" gauge track.
I designed this to be laser cut from 3mm acrylic with 3d printed wheels.
The instructions for making one of these are available on https://pinevalleyestate.com/2024/01/19/a-3-5%e2%80%b3-gauge-motor-trolley/
