John Bromley. Cima Hill is among the steepest grades that Union Pacific trains face on their march across the continent, reaching over 4000' at the highest point. Here we see a long mixed freight descending the hill, using every means possible to claw the rails and maintain a 20 mph speed limit to avoid a "runaway." This limited edition print measures 24"x 16 and is signed and numbered by the artist. #0R07178
