Paperinik77pk posted a topic in LEGO Train TechHi all, since I read the very, very interesting thread about Torben Plagborg creations, I've been trying some new designs (some are just sketches, just to understand how things could work). Now, in this nice thread some nice 12v creations can be seen - but one captured my interest more than others. It's a little blue steamer with a black 12v motor. It seems pretty big, so I'd say it was an 8-wide experiment. In general, all the top shelves are very interesting. Starting from that little steamer, I began to think about a 12v locomotive in 8-wide. So I started designing another small steamer (I'd say a well known prototype): the great Deutsche Bundesbahn BR-80. 8-wide is not a common scale for me - I only tried it two times in my whole life, so it was a trial and error process. I tried to use parts that could have been available in the last 80s /first 90s - during the Phase II of the Gray Era and the advent of 9v era. And here it is...it recalls me a "fat" 7727/7730, with a touch of 7810... 8-wide gives some possibility also to work with odd number of studs (boiler is 5 studs wide instead of the classic 4-wide used in standard 12v steamers). I kept the standard cylinders, the ladders, rods, red buffers and magnets, which fit nicely an keep the 12v feeling alive. I used Some SNOT for the doors, using headlight bricks. Everything was already experimented at the time (e.g. the B-model wagon with horizontal sliding doors in 7735 instructions). Right side is quite symmetrical to the left one, apart some details. 12v motor looks nice, now that the body is correctly larger. Weights can sit on top of the motor - but the model could already be sufficiently heavy to have some decent traction and pulling power. I think adding lights won't be a problem nowadays, but for sure at the time (80s/90s) it could have been an additional challenge ! But...there are some issues that must be noted: The buffers overhang is quite...massive - and this SURELY will create problems with 12v switches, since the buffers will collide with the switching electric mechanism. Coupling wagons on R40 curves could be impossible...since this BR80 is longer than any other 12v locomotive or wagon not based on bogies chassis. Weight of a complete train could be excessive for the poor 12v motors. I think it has been a very fun experiment, a real "12v+" MOC...but being realistic - in my opinion it's too limited by the motor, wheels size...and 12v track geometry itself . Maybe, with 3d printed 12v wheels and a PF-based motor it could work on PF flexible track - but it would then loose 90% of its "vintage" appeal. I'd classify it as "Virtual Shelf Queen" ! Ciao! Davide
