The Chicago, Burlington & Quincy ran a farewell-to-steam excursion on July 17, 1966, from Chicago to Denrock, a railroad junction in Illinois near Rock Island. Photographers and families crowded the right-of-way for a photo runby with coal-burning locomotive 4960, built by Baldwin in 1923. Today, the same locomotive pulls excursion trains several times a year at the Grand Canyon Railway in Williams, Arizona. Same locomotive, but a new fuel, recycled vegetable oil. Its trip on September 17, 2011, marked a celebration—the 110th anniversary of the arrival of the first Santa Fe train at the canyon rim. The photo appears on the cover of Railroad Heritage 26, "Railroad Preservation in a Nutshell."
