Open Source Railroad – not to be confused with OpenRailway Project, which is a bit contradictory to its name – marks a new chapter in the world of true open source 3D printing. Thanks to Tinkercad, the app which was used to create the project, you not only get access to print-ready STL's, but also to the easily editable source files. There's no complicated CAD software to learn or download – simply launch your browser, modify as you wish, export to your printer, and start building!
MUNI Metro Train (Breda LRV HTK5) detail photos.
Finding information on MUNI's trains proved to be a challenging task. Sure, the internet is filled with hundreds of low resolution exterior shots of these light rail vehicles, however there was nothing in terms of blueprints or detail shots. This forced me to go out on several occasions and take these photos myself. And unlike most of the other more common LRV's and locomotives which service the Bay area, Italian manufacturer Breda had built only about 151 of these specifically for San Francisco, which would explain the rarity of information available online. Let's just say that I'd love to visit the repair shop, in case someone would be willing to offer a tour!
After some digging around I was able to find a drawing, however after comparing it to the real thing, I've realized that several important features weren't represented as they were on the actual train, which further pushed me to generate my own drawings from several high resolution photographs which I had taken.
I'd love to hear your feedback in the comments!
