This train is a
“matched” train, the motor is the only component
fitted to the loco thus the tubs cannot be separated from the loco. I made it this way as there was no room for the batteries plus the receiver and ESC inside the loco.

The loco is an old MDC ‘Roundhouse’ Big Hustler model bought secondhand when I first started out.

| Loco and Tub |
The tubs are made from PVC end caps and pipe with angle styrene around edges and card making/craft embellishments to simulate rivets covering joins. The tubs are mounted onto pieces of pine for chassis, with the axles running in 4mm irrigation riser attached to the chassis by cable clips. The wheels are from a toy train.

The gravel is bonsai pot "toppings" glued to pieces of balsa sheet.
