There are many Special Interest Groups that allow those who share like interests to share thoughts and passions about facets of the hobby. They are usually referred to as SIGs for short. These are different than the typical RR historical society that focuses on one specific line. Some include topics such as operations, layout design, early rail, and the Civil War.
In future posts some of the SIGs will be explored in more detail and maybe one will appeal to you enough to join that group.
