1:24 3D Printed GE U10b (NZR Dh class)

1:24 3D Printed GE U10b Dh class. Pre-shunters refuge and painted as she came out new. Unsure of her number yet, will have to find out which Dh resided in Whangarei in the 80/90's. For the chassis i'm using a 4 axle power truck, Aristocraft I think.

After a lick of red and yellow. I've been using cans purchased from Wynn Fraser paints (Don't tell em your painting trains at night time - really bad idea I found..). The brand is "RUST-OLEUM" paint & primer in one, worth $13 a can normally. For the NZR fruit salad scheme i'm using Satin Granite(grey), Gloss Apple Red & Gloss sun yellow.  For the modern Kiwirail colours i'm using Lemon Yellow, & Gloss Dark Grey. I still haven't found a match for Kiwirail red, which is quite orange in certain light.  
I'm quite keen to do a Da next, in the original scheme. Would look great on the head of a silverstar set!


Printing a Dh in 9mm (1:33.9 scale) for a customer (Centre image), after gluing sections, bogging, sanding & covering with Satin Granite primer/paint it came out quite well. Tempted to print it in 1:64 just to see how the detail might survive..
After adding trucks/bogies, one powered, one dummy.
A wee video of the 1:24 Dh test run, using a similar power block as the dsg, they make a good pair.

  1. Funnily enough, both the KR and TMS red are the same, and yes, they are far more orangey than red when fresh.

  2. Cheers Kiwibonds/db for the clarification :)

  3. What wheel diameter did the real thing use? Plans of little export GEs say from 34" to 40" wheels so it obviously varies.
