End of an Era: Honoring the Legacy of Thomas Built’s D Line

For more than 50 years, Thomas Built Buses' original plant was home to the iconic Type D transit-style school buses—the Saf-T-Liner® HDX and EFX. Now, we close the chapter on the D Line and take a symbolic and literal step into the future of bus manufacturing. In this commemorative video, we honor the final HDX/EFX bus to roll off the historic assembly line with a look back at the legacy, the people, and the pride that built it. Featuring interviews with long-time employees, from plant managers to welders to executives, the video captures a moment of transformation—where memories were made, the interior was signed, and the journey forward began. The D Line at our legacy plant may be ending, but its spirit lives on in the next generation of Type D buses: the HDX2 and EFX2. Built on our most advanced line yet, these buses represent the continued innovation and craftsmanship Thomas Built is known for. 💛 Because at Thomas Built Buses, every mile matters.
