Home Events About Gallery Welcome to the Slim Gauge Guild. We have two layouts located in a 2000 square foot basement. The HOn3 layout is based on the Denver and Rio Grande Railroad and the Rio Grande Southern. On the HOn3 layout we tend to model specific prototype scenes. The Sn3 layout is more freelanced. We tend to model scenes as we see fit. We do loosely model the Colorado and Southern for our mainline and northern California lumber companies for our highline. Membership: We are currently looking for new members. If you are interested please contact Jeff Smith Slim Gauge Guild is located at: 300 S.
