  1. Thanks for the reply :) Regarding the elevation: 12 Bricks in one spiral is the minimum I've got from testing. The linked example picture runs with 15 bricks per rotation, so I'm optimistic about it working. Greetings, Afo
  2. Hi guys, I'm planning a Lego diorama with a mountain range. Within one of the mountains I plan to place a lego train spiral. Heights and height differences make train mocs just pop. Do you have examples of how to build a train spiral anchored to base plates (imagine 4 48x48 plates)? To my amazement I couldn't find a single example on google images: Noone builds train spirals on base plates. All spirals fall into three categories: 1) The tracks are on a nonlego structure, mostly wooden supports. 2) The tracks are on a lego structure, but that structure is not on studs, but flat ground. 3) And the third one is this crazy outlier that uses Lego bending: http://www.nalug.org/TrainShow2006/Spiral/spiral01bm.jpg And when I entertained the idea, I came across a possible problem. If you change a circle to a spiral but you only have the same length, you change the diameter/radius. Does this change the layout or puts the entire structure under so much stress, that it's simply problematic to set up? Calculation: Imagine a classic circle based on curved tracks. You have a radius of 40 studs/32cm or a diameter of 80 studs/64cm. If you abstract it as a string you can imagine it as a flat circle or with an incline. This leads to two states: Flat track:Circumference 201 cm Spiral:Height (12 bricks equal) 11,52 cm, Imagine unwrapping it while keeping the incline. Then you are left with an easy pythagorean theorem with a hypothenuse of 201 cm. This leads to a circumference 200,67 cm. This leads to a difference of 1,08 mm (1 stud equals 8 mm) in diameter. This leads to some stress I might want to mitigate by not anchoring the entire structure, but not to changing the layout (going down a stud in diameter or something along those lines. Hope you can help, greetings Afolomus

    Hi guys, I'm Afolomus, a recent returnee to the hobby. My childhood Lego from the late 90's and early 00's is thankfully still there. After building up a few of my favorite models from the pirates and star wars themes I came back to the theme I missed the most. I always wanted but never got 4559. So now with a little bit more spending money I went out and found the extremely impressive MOC scene as well as the brick trains sets from Bluebrixx. After endulging a bit, I wanted to wrap it up in a bigger project. And that's where I am now. Bought lots of used Lego and planning a 7x9 base plate train world at the moment. Greetings from germany
