The EMD SW 1500 is a American diesel switcher locomotive made by General Motors' Electro-Motive Division during the 60's and 70's. Some 800 were made and there are several still in serivce in the United States.
This 1:32 scale version of the EMD SW 1500 locomotive is part of "The OpenRailway Project" which is a Open Source initiative to bring more free model trains to the world. While having done several different 3Dprinting projects in the past i needed something with a little more attention to detail to 3Dprint. Since me and my dad had already built a garden railway (scale 1:32) it felt like a good idea to go for a train. I went to a model train store in Stockholm to discuss what train that might be suitable and after two or three cups of coffee i decided on the EMD SW1500.
Design work began by searching for specifications, drawings and pictures. While i didn't have very much luck finding the kind of drawings I initially hoped for (I did find a few) I had to rely heavily on different photos hence some details may be incorrect. Everything is 3D-printed but the handrail which is made from 1.5mm Aluminium welding rod. The are some details that need attention but basically you can print and assemble everything if you want to own your very own 1:32 SW1500.
