    Hello BigJake,

    do you know the Kato # 20-??? for a piece of 22,5 degree with superelevated track, not the 20-182 transition ?
    I think for 1 modul 20-182 L / 20-181 and a piece of 20-??? , this is more easily transportable.
    Or I have to separate the 20-181 in 2 half.

    Rainer,

    AFAIK, there is no Unitrack non-transition, 22.5 degree, superelevated, doubletrack section of any radius. The 22.5 degree pieces are all "easement" (as named by Kato*) pieces that transition between SE & flat track.

    Also, 22.5 degree curves, unless always used in pairs, do not work well with their family of 15, 30 and 45 degree increments for the rest of their track sections. Since the easements must be used in pairs, that makes them effectively 45 degrees together, to maintain the 15 degree increments with other curves.

    Kato has a complete listing of their N scale Unitrack on their website http://www.katousa.com/

    This restriction in making any SE doubletrack layout curve, including easements, be a multiple of 45 degrees is a big limitation for many non-modular layouts.

    At least one vendor of 90 degree super-elevated T-Track modules recommends for 180 degree curves, leaving the middle 45 degree SE Unitrack section (that would span the two 90 degree modules) removable, to allow separation of the two 90 degree curve modules for easier transport.

    This also allows their modules to be used as separate 90 degree curve modules, by replacing the removable 45 degree SE section with two 22.5 degree SE easement sections (one on each module, for a total of two easements per 90 degree module).

    *"Easement" is typically used in MRR to refer to a short section/area of increased/increasing radius, between straight (aka "tangent") track and the remainder of the curve. However, the term "easement" applies to "ease the transition between two types of trackage, whether they be SE and flat, or curved and straight.

    I should have noted that there may be some additional Japanese Kato Unitrack products which are available from Japan via internet in the US, but katousa.com only shows what they distribute in the USA.

    I really wish Kato would make all their products available here. I know there are quite a few European and Japanese models I would love to have but not really interested in paying some of the import markups.

    Try Plaza-Japan on eBay. They don't jack prices and is very reliable. Fair shipping charges too.

    Made the first container for my future intermodal facility.

    Where did you get the STL files for them or did you design them yourself! Based on the picture I'm assuming filament and not resin?

    The files were from Thingverse and I am still looking for a better file. For some reason it only prints the corragations on one side of the container.

    Yes this is a filament print, I didn’t really need super detail for this job. Even the missing corragations won’t matter much for this project.
