Almost a year ago, I shared instructions for building a LEGO shipping container—a simple but versatile design that can slot neatly into your cityscape, industrial layout, or train yard. Clearly, what is missing is a train wagon to carry those containers! I did have a wagon design shown below; however, it was not a design I felt was suitable enough for instructions at the time. Thankfully, I have finally taken the time to revise the design and produce instructions, which is the main topic for this article! This LEGO wagon is loosely based on the British Rail FGA container flat wagon, but it is generic enough to represent any single-deck “con-flat” wagon. The real-world FGA wagons were designed in the 1960s to carry standardized freight containers across the British rail network. My LEGO version borrows the same open-frame structure and container pad layout, but with a build streamlined for both simplicity...
