[MOC] Full Lego Technic locomotive - in 1:22,5 scale
Paperinik77pk posted a topic in LEGO Train Tech
Hi all, these days I'm working a lot with Lego Technic, since I've bought some parts to experiment a bit this new world. I'm used to build old Lego Technic from the 80's and 90's...but these new sets are very very complex, and require a lot of time to figure out where and how to put a certain part. So , back to the Stud.io I started designing again...and came out with this thing: It's similar to old steam trams, to the GE 2/2 and HGE 2/2 locomotives, to some service railway cars...to the alternate 7720 model. Oh, well...it's a box and it's similar to all those boxy things! Dimensions are 13/14 stu...holes, units? for width and 25 for body lenght. Both buffers add an additional 6 studs to overall lenght. I'd say it is a small 1:22,5 locomotive, like my old yellow shunter with PuP. Since I'm still not so much able to recreate details such as doors and ladders...I simply avoided them. Pantograph is designed to use a rubber band for the moment - it could be nice to make it foldable with some gears! At least the body is self-consistent and can easily be removed. The battery is fixed on the central upper part of the body, right in the middle to increase weight on all 4 traction wheels. Rods are somewhat triangular and quite strange, but they're strong! Other kinds of rod arrangements can be done. Using a normal gear transmission could also avoid rods at all. The boxy body gives me the internal space to experiment for transmissions and motors. This chassis probably will change a zillion of times like the one of my XXL locomotives. In the picture above, you can see the possibility to have the double gauge solution (left axle is L-Gauge and right axle is configured for 45mm G-Gauge track). The gear you can see in the middle of left axle shows the possibility to implement a cog railway system using Lego flexible track. I sincerely do not know if the 45mm cog tracks could work with a Lego gear - so let's limit the cog solution to original Lego track It can become also a fancy Tram locomotive, like the "Gamba De Legn" ("Wooden Leg") used in Milan for many, many years. But for this one - I'm still struggling to create a proper, working engine. I've seen few full Technic locomotives, but it's really fun to build them! I hope you like it!!! Ciao, Davide
