Custom MOC Train Track Set

The ZITIANYOUBUILD 423 MOC-117831 is a custom building set designed for hobbyists and builders aged fourteen and up. It provides four hundred and twenty-three pieces to construct a detailed MILS ballasted double track model. The set arrives new with PDF instructions for assembly.

100% LEGO Compatible Bricks

Every brick in this set is manufactured to connect tightly with standard LEGO elements and other major building block brands. The pieces are made from durable ABS plastic that is BPA-free with smooth edges. This compatibility allows the track sections to integrate directly into existing LEGO train layouts or modular city builds.

Four Hundred Twenty-Three Pieces Included

The part count supplies enough track sections, ballast elements and structural pieces to complete the specified double track model. Builders can assemble the designed layout or recombine the elements for custom track configurations. The finite inventory means larger continuous circuits or complex yards will require additional sets or spare parts.

Questions about this item

What does the MOC-117831 designation tell me about this set?

It identifies a custom My Own Creation model using 423 pieces to build a ballasted double-track train section.

How does the LEGO compatibility work in practice?

The ABS bricks are moulded to the same dimensions, so they clutch firmly onto genuine studs and accept standard plates without gaps.

What baseplate size does the finished track need?

The model is designed around the MILS modular standard, so it sits on standard baseplates and connects to adjacent MILS modules on a flat surface.
