[MOC] Ferrovia Eritrea Gruppo R.202 0-4-0T in 1/22.5 - now with track video
Sven J posted a topic in LEGO Train Tech
Edit: New video here. Dear trainheads, Some time ago EB member @Plastic_Goth presented his digital model of Ferrovia Eritrea's Gruppo R.202 shunter. I immediately fell in love with that cute little prototype, and I knew I had to build a model myself, in slightly larger scale for 45 mm garden railway track. Well, here it is! The prototype was built in 1927 by Breda in Milan, Italy, for shunting service on the 950 mm narrow gauge lines in Eritrea (which was an Italian colony at that time). In total, eleven class R.202 engines were built; several lococomotives are still in operation today (the „R“ stands for „scartamento ridotto“, narrow gauge). My MOC represents a R.202 locomotive in ca. 1936, after the original lifting injectors (inside the cab) had been exchanged for non-lifting ones (below the cab), but before a new numbering scheme was introduced, dropping the „R“ in the class designation. The model is held in accurate 1/22.5 scale and driven by a single L-motor working on the second axle. It features front and rear lights (from Brickstuff; separately controllable for the left and right engine side) and a Seuthe no. 99 smoke generator. All funcions are powered and remote-controlled by a BuWizz 2.0. The rods and valve gear parts are 3D-printed parts of my own design. The model consists of approx. 1,400 parts and weighs just over 1 kg. Compared to my previous models, it is much easier to handle and maintain, due to its "small" size, but still has amazing pulling power (10 four-axle LGB cars are no problem). So I think it will become my standard "everyday" engine... And here are the pictures: Prototype data sheet (drawing not accurate and not to scale): While the fireman is carrying out a minor repair on the smokebox door, an administrative officer arrives in his brand new Fiat Topolino (modified design by Peter Blackert): Two tiny Italians... Some views of the cab interior. As the BuWizz is located in the position of the firebox, the roof and the boiler backhead can be removed for access to the power button and to the charging socket: The frame: Three weight bricks are installed inside the frame and boiler, thus increasing traction: The half-plate offset in radius between smokebox and boiler required some unusual (but surprisingly sturdy) SNOT-work. A video of the model on track will follow. For now, here is a short sequence of the engine on the roller test bed: More and high-resolution photos can be found in my Flickr album. Comments and criticism are most welcome. Thanks for your interest! Best regards, Sven
