3D-printed DDA40X locomotive (Scale 1:32) for the garden railroad *UPDATED, December 29th – 2016*

While I’m still waiting for some paint and motors to arrive from China, to finish the EMD SW1500, I already started drawing / partitioning / slicing / printing a new one 🙂
This time it’s also an American diesel locomotive, namely an EMD DDX40A. (also called “Centennial” or “Big Jack”)
This is the largest diesel locomotive ever built. In 1:1 scale, it measures 30 meters, and does have 6600 HP under the hood ! So, in scale 1:32 it will be about 94 cm long !

I already have several parts printed, I hope to start construction next weekend 🙂

Update- november 22th, 2015

Well, today was one on those days … Heavy rain and dark clouds the whole day. So, it was time for a “lazy sunday afternoon” 🙂 I couldn’t resist, and started building the DDA40X together. Cabine is ready, and half of the motor/generator compartiment. (Yes, that’s right, only half !) So, it’s going to be almost twice as long as the current build-status …

Update- november 26th, 2015

Today, the last part of the chassis got printed, so after work, I started glueing the chassis together. We tried a dry-fit for the upper part (cabine and motor/generator housing) on the chassis, and couldn’t resist to take some pictures 🙂
(you may see a small gap on the pictures between the chassis and the upper part, this is due to the fact it’s not glued in place yet. (Still need to be able to access all internals for placing electronics, interior for the cabine, LEDs, fans etc …
I’m still strugling with the bogies, but hey, I’m sure this locomotive will be ready before Christmas 🙂

Update- december 29th, 2016

I gathered all STL files and pictures, did put them in one big ZIP file, and uploaded them to thingiverse.
You can now print yourself a DDA40X from the following link:
