The depot, c. 1857, is home to Herndon Historical Society.The Herndon Museum houses railroad memorabilia, information on Commander William Lewis Herndon, for whom the town was named; and artifacts from local residents. Operated by the Historical Society of Herndon, the building dates back to the 1850s and served as a train station until 1968

Herndon Historical Society meetings are free and open to the public, and visitors are always welcome. For additional information contact Society President Carol Bruce at carolbrcom@aol.com.

The Society sponsors the historic home registry program designed to increase public awareness of Herndon’s older homes and buildings and their contribution to the Town’s distinctive character and spirit. Once an owner documents the history of the home and demonstrates that it satisfies certain criteria—such as the original structure being 50 or more years old and compatible with the character of Herndon, as well as being of historical or architectural significance to the Town—the application is approved and a request for a resolution is submitted to the Herndon Town Council. Once the resolution, which certifies the historic significance of the structure, is adopted, the structure is eligible to receive a plaque. All documentation becomes part of the Society’s research library, and a picture and brief history are placed on the Historical Society’s website

In 1989, longtime Society member and railroad aficianado George Moore located a surplus Norfolk and Western caboose, arranged for it to be transported to Herndon, and coordinated with the Herndon Department of Public Works to install the section of track on which it sits. Located adjacent to the W&OD trail—formerly the W&OD railroad line—the caboose serves as a reminder of the town’s rail history. Although the caboose is now the property of the Town of Herndon the Society continues to monitor its condition and to fund the interior maintenance. Following his death in 2003, the caboose was dedicated in George’s memory. In 2008, the interior was restored and the windows were improved to make them water tight.

Each December for the last few years the Historical Society, along with the Herndon Foundation for the Cultural Arts and the Herndon Chamber of Commerce, has sponsored an Annual Model Train Show. This event—which is held in ArtSpace, Herndon’s community art gallery—features both HO and N gauge model trains.

In 1999, the Historical Society funded restoration and improvements at the gas generating facility located across from Herndon’s Municipal Center. Improvements included a display that explains how the facility operated, along with landscaping for the mini-park that surrounds it. The park is dedicated in memory of former Society president Larry Clarity, and the benches it contains were donated in memory of another longtime member, Bill Moffett.

The Herndon Historical Society was founded in 1971. Its purpose, as stated in the Society's constitution, is “…to bring together those people interested in history, and especially in the history of the Herndon, Virginia, area.”
