Price $999.00. - After release date (May31st 2025), the price increases to $1450.00


The kit will be released in late May 2025.

In the meantime instructions will be slowly uploaded for modellers to read and understand.

These should start being placed on this page and on the facebook page - NSWGR Z20 Steam Tank Locomotive, during April 2025.

The Z20 Loco Kit is built on an Etched Nickle Silver frame, 3D printed parts, mastered into Brass Castings.

Slaters wheels with a Roxy Mouldings 40:1 gear box driven by a Mashima 1833 motor.

I have made 3D prints in clear plastic for head lamp inserts and the back head sight glass.

The inserts will accept small LED's or fibre optics.

The kit will have 2 options for speakers and will have advice as to what DCC sound decoder will be suitable to add to the kit.

Either a small oval speaker in the bunker,

which can be easily boxed in, or a Sugar Cube speaker at the base of the smoke box, with the Smoke box designed to fit the speaker.
