Yes Vaughn is a "hot spot" it is on the BNSF (ATSF) main line with the UP-SP Tucumcari line crossing under it just west of town. If you are looking for the BNSF just follow US60 from Amarillo Tx to Belen NM, with "hot spots" at Clovis, Fort Sumner, Vaughn, Encino, and Abo Canyon. If UP-SP follow I-40 Tucumcari to Santa Rosa then US54 to El Paso, with "spots" at Tucu., Cuervo, Vaughn, Duran, Corona, Carrizozo, and Alamogordo. All of the semaphores on the UP-SP may be gone, but if any are still there it will be at Duran.
