[MOC] 1:22,5 Scale - G Gauge (45mm) - Toy Locomotive (Mark II) and new LGB-based "gondola" wagons
Paperinik77pk posted a topic in LEGO Train TechHi all! Here we go again with big Lego trains running on 45mm G Gauge track! Some of you may remember the yellow Toy Train locomotive I prepared back in 2019 -it was one of my first experiments with G-Gauge trains. This little locomotive was based on a small Powered-Up battery box and a Medium motor. Here it is during a night run on the new 45mm copper track with wooden sleepers I restored to be used on my small garden railway. Here's a detail of the old chassis with the original 1,667:1 gear ratio. This solution proved to work fine on a flat track at home, but was completely useless on the garden line, which can be easily considered a "mountain railway". A 3:1 gear ratio worked better, but gears were too stressed and speed was ridicolous. Plus, with some wagons, the motor always needed to work at full speed. Therefore, back to the lab, I completely revisited the heart of the locomotive, and updating some details on the exterior. Here it is, the Mark II (TADAAAAAAA) !!! And...what's new??? Actually, at body level, it did not change so much from the older one . Handle bars, and headlights have been modified and a new exhaust scoop has been added over the hood (there's no more a red On/Off button). The real new part is under the bodywork: A completely new chassis has been introduced, and now features a new 4-ports PuP Hub and a more efficient Large Motor. Gear ratio is now 2.779:1. It is very strong and smooth - the big battery/bluetooth hub helps traction (which can be increased with the use of rubber bands around the wheels), and the L-Motor is a great improvement over the M-Motor. I've prepared some workflows on the PuP application to work at 25/50/75/100% of the power. The chassis can be detached from the body with four "fast unlock" pins, so changing the batteries is now an easy task. Then, with a locomotive now up to the task of garden railroading, I needed some rolling stock. I've some LGB wagon bases with studs on top (item number 94063) which are the perfect chassis for some wagons I've designed in Stud.io. Both axles are steering, to help the wagon working on tighter curves. So here it is the small gondola , in a bright blue color: And the tan/beige gondola with taller sides: The LGB chassis runs smoothly and really helps the whole train to roll better. Sometimes these things are available (used or new) with an acceptable price, so I get them. A final photo of the consist (fat least for the moment)! Next to come, a passenger and a closed freight wagon with sliding doors (let's see who comes first). I'll try it on the garden railway soon and give some feedbacks (for now only some pretty satisfactory tests were conducted on homemade ramps) I hope you like it!!! Ciao! Davide
