What it does

Prints as one piece so you get a finished container ready to place on your layout right away
Compatible with PIKO flatbed cars through bottom pins, so your intermodal trains look realistic and connect properly
Choose flat or corrugated roof design so you can match the level of detail your diorama needs
Measures 69.8mm long and fits HO scale standards, so your container sits right alongside other model railroad pieces
Pins cut off easily if you need a standalone piece, so you have full control over how you use it

Build a working intermodal yard on your model railroad layout. This HO scale 20ft container prints as one detailed piece and drops straight onto your PIKO compatible flatbed cars. You get the realism of corrugated walls and roof that match real freight containers.

The design gives you two options. Pick the flat roof version for easier printing, or choose the corrugated roof when your layout calls for extra detail. Dimensions run 69.8mm long by 28.7mm wide by 28mm tall, so the scale sits perfect with standard HO model trains. Small pins on the bottom slot into PIKO wagon holes, or cut them away in seconds if you want the container to sit loose on your layout.

Wall corrugation prints symmetrically and accurate to real containers. This works as a single piece on your diorama, a switcher yard piece, or part of a loaded consist rolling down your mainline.
