Photograph taken for a newspaper owned by the Oklahoma Publishing Company. Caption: "This Heavy blade was wrenched free and hurled through the air by the force of the crash. A 48-year-old street department employe was critically injured Saturday morning when his road grader was struck broadside by the engine of a 124-car Rock Island freight train at a crossing near SW Linn and California. Taken to Mercy hospital suffering from a severed right hand, concussion, severe head and internal injuries was Hubert J. Dickson sr., 301 SE 41. His condition was termed "very grave" by physicians. Dickson, according to witnesses, was pinned in the wreckage. His right arm was severed between the hand and elbow. The street department road grader was demolished in the grinding crash and wreckage was strewn along both sides of the railroad bed for several hundred feet. The engine of the train also was heavily damaged. Street department officials said Dickson had been operating the road grader on Linn street. He apparently did not see the approaching freight train in time to avoid the collision."
