Next MOC: 1:33 GHH G7.1 (0-8-0) steam locomotive with PF
Tenderlok posted a topic in LEGO Train Tech
Hello AFOLS, the next MOC I would like to share is this 1:33 scale 0-8-0 steam engine similar to the Prussian type G 7.1 (https://en.wikipedia.../Prussian_G_7.1). The "Gutehoffnungshütte" (GHH) colliery and iron works company in my home town Oberhausen, Germany, had a total of 13 of these simple and reliable locomotives, which differed from the Prussian State Railways engines by having a slightly increased boiler pressure and therefore being a bit more powerful. They were used for hauling ore trains from the Rhine harbour in Walsum to the iron works as well as for pulling shuttle trains for the GHH workers. Sadly, none of the GHH G 7.1 locomotives has survived. Finally, I moved into an apartment where I have room for a track layout, so the model features two PF L-motors, a rechargeable battery pack and a V2 IR receiver. As I wanted to create a highly detailed frame for the locomotive, all PF components are squeezed into the tender; to achieve this, while still retaining a realistic outer shape, was quite a challenge, but I think I found a very satisfying solution. The drivetrain layout enables the engine to reach a true-to-scale maximum speed of about 0,5 m/s, which is equivalent to approx. 60 km/h. As the prototype had Allan valve gear inside the frame, only the main and side rods are visible on the model, too (for German steam engines, it's quite unusual to have the side rods painted black, but it's authentic for this particular prototype). The model runs on standard LGB track (45 mm) and is capable of negotiating R3 curves and switches. The distance between locomotive and tender can be adjusted (the photos show the prototypic close-coupled adjustment suitable for display). I used a few non-LEGO-parts: BBB XL drivers (engine), BBB L drivers (tender), rubber band around the smokebox door, thin PVC washers on the crankpins (to prevent the side rod bearings from jamming at the wheel rim), and homemade stickers. And now the pictures: Not quite purist, but I like this photo: The engine frame, showing leaf springs and brake rigging: A glimpse of the cab interior: Boiler backhead: Tender internals: More and larger pictures can be found here. Finally, here is a video link for those of you who would like to see the model in action. I apologize for the poor quality, but unfortunately I do not have a tripod. Some rolling stock will come soon. Best regards, Sven -
... or at least that was what it was supposed to look like [EDIT] V2 with LDD file [/EDIT] Hello all, This is my latest steam engine, based on a USRA 0-8-0. USRA 0-8-0 by UrbanErwin(EPJL), on Flickr It features BBB Medium drivers. The thing is powered by a M-motor, and receives current through a emptied 9V train motor (don't worry, it broke before I took it apart) It features some pressure gauges. USRA 0-8-0 by UrbanErwin(EPJL), on Flickr I originally intended to add a decoupler based on this design, but the tender would become too long to look good with the engine itself. The light gray area is for a logo which I still have to create and print. USRA 0-8-0 by UrbanErwin(EPJL), on Flickr More pictures Thanks for looking, improvement points are appreciated
