The Brotherhood of Locomotive Engineers and Trainmen (BLET) is the oldest labor union in the Western Hemisphere, tracing its roots back to the mid-19th century. Initially formed as the Brotherhood of the Footboard in 1863 by Michigan Central Railroad engineers, it was renamed the Brotherhood of Locomotive Engineers (BLE) in 1864[1][3]. Over the years, the union has evolved, and in 2004, it merged with the International Brotherhood of Teamsters, adopting its current name[4]. The BLET's formation was driven by the need for better working conditions and fair treatment for locomotive engineers, who faced harsh conditions and exploitation by railroad companies. The union has played a crucial role in improving workplace safety and advocating for legislative changes. Notable achievements include the passage of the Locomotive Inspection Act and the Adamson Act of 1916, which established the eight-hour workday for interstate railroad workers[1][3]. Today, the BLET is a founding member of the Teamsters Rail Conference and represents approximately 51,500 active and retired locomotive engineers and trainmen across the United States[1]. The union continues to focus on promoting and protecting the rights, interests, and safety of its members[6]. Recent leadership changes include the appointment of Mark Wallace as the National President, effective May 1, 2025[1]. The BLET remains relevant in modern times by addressing contemporary issues and engaging in educational programs. For instance, it participates in historical and diversity-focused programs through the Teamsters History Project, highlighting the union's role in the broader labor movement[8]. Despite its long history, the BLET continues to adapt and advocate for its members in the ever-changing landscape of the railroad industry.
