Excelelent work. The R means "revisited" G8/12. GR12 have another tecnology, different from an older G12. Ttrucks sideframes that you can use must be an SDL39(Overland? Kaslo?) or spanish JT16 from Roco with minor mods.

Looks very similar to one of the models CN used on the narrow gauge lines in Newfoundland up until 1988. I believe all of the ones which were not scrapped were sent south to Mexico or South America. I think one (G8?) survives stuffed and mounted in Colorado: maps.google.com/maps?q=39.908539,-105.240516&ll=39.908479,-105.240488&spn=0.000421,0.000573&num=1&t=h&z=21Hi there. Not to be picky, but I can see build lines from the 3D print in your resin casting. Next time, try www.moddler.com and have john run your print at 16micron resolution. the print will look like the smoothest, best molding you have ever seen. A great project otherwise! Cheers, Chris

Hi Chris You are not the only one who can see some layering from the 3d printing process. But fortunately, these layers were most noticable on the frame skirting, cab sides and roof. These parts are pretty plain, without many surface details. Therefore it was no big issue to fill and sand these areas. Interestingly, the hood sides with all the doors only showed very little signs of layering - our luck! The printing for the GR12 was made some two years ago. We know that the technology has made huge progress in this short time frame. Next time we do something similar, we will have much better opportunities than we had when the GR12 parts were printed! I will soon post some new pics.
And yes, we know about the Frateschi models. But first, These models are not true 1:87 scale, but rather something like 1:76 (British OO-scale). And then they are G12 four motor types and not six motor GR12 types. And you know, if someone wants a true scale SD40, an out-of-scale GP40 won't do...
Kind regards Beat (Rednorte)

In the meantime, the GR12 has received some paint and is now wearing the pre-1980s scheme of the former Ferrocarriles del Estado del Chile. Maybe she is looking somewhat tired, no wonder after a long ride through the Atacama desert... Beat
