Gauge refers to the distance between the rails on railroad track.
To attach figures use Scenic Accents Glue. This adhesive is specially formulated for instant placement while allowing time for repositioning and leaving no puddles or residue.
Most of our AutoScenes® and Scenic Accents® are designed to fit into a 1940s - 1950s era.
We recommend using cyanoacrylate adhesive (CA glue/super glue) to reattach broken pieces on a Scenic Accent. Use only a very small amount, a little goes a long way. Apply with a toothpick and press together. Hold until setting begins.
The figures in the Economy Sets are randomly selected. In the Assorted Figure Set, the figures represent common positions such as, walking, sitting and standing.
