The Brotherhood of Railroad Signalmen (BRS), founded in 1901, is a labor union representing over 10,000 signal employees across the United States and Canada.

Signalmen undergo extensive training through a combination of on-the-job experience and formal apprenticeship programs, which cover federal regulations, railroad operations, electronics, and mechanics.

The BRS is headquartered in Front Royal, Virginia, and operates through a network of local lodges that represent members employed by specific railroads or divisions.

The union is affiliated with the AFL-CIO and its Transportation Trades Department, emphasizing its active role within the broader labor movement.

Vice Presidents include Tim Tarrant, Cory Claypool, Kurt Mullins, Quinn Norman, Brandon Elvey, and Doug VanderJagt.
