For my HO scale layout, my Dad and I are building a replica of the Belt Railway of Chicago (BRC) shop building. While not an exact duplicate, we are trying to keep many of the architectural features. Because of this, we had to create custom trusses for the west section of the building. This truss is an HO scale 60' wide and 16'3" tall. The side sections are 21' each and the middle section is 18'.
