Potomac Chapter membership includes individuals interested in many aspects of railroading including historical and current operations; steam, diesel, and electric power; historical research; riding trains; rail photography both still and video; historical preservation; railroad stations and structures; and model railroading that spans various gauges. Our monthly meetings in Rockville, Maryland, feature programs on rail topics of current or historical interest. Programs feature a guest speaker or presenter and include an audio/visual component of railroad slides, digital photos, video, or movies. We’re very proud of our monthly newsletter, Potomac Rail News. We contribute to local railroad-related preservation efforts and our annual Chapter activities include a banquet, a picnic, and occasional field trips. The Chapter was founded in 1970 and visitors are always welcome.
