Santa Fe 2130, in from La Junta, idles at the Pueblo engine terminal. By December, 1964, Santa Fe’s 53 Alco RSD5s are running out their final miles in Colorado and New Mexico freight service, assigned to locals and the occasional helper turn over Raton Pass. A few will be rebuilt into unpowered “drones,” but the 2130 in six months will go to EMD in trade on a new GP35.
