About the 3D snapshots

Rendered from the existing track models with BrickUpp’s catalog material and lighting profile and an orthographic top camera. Model references: LDraw, L-Gauge, and Fx Bricks. Trixbrix specialist diagrams come from the BlueBrick 2D library and retain its source scale; they are not 3D renders. Catalog counts describe documented matches, not live stock.
