Utah Railway train HUTAHJ-14 threads its way through the "gate" at Castle Gate, Utah, on march 14, 2015. (There used to be a similar cliff on the left, until it was blown apart to make way for US Highway 6 in the 1960s.) Leading the train is MK50-3 5003, followed by a pair of EMD/Clyde SD50S locomotives (6064 and 6060) and two more MK50-3 units (5006 and 5005). The MK50-3s are rebuilt/repowered MK5000Cs, and the SD50S diesels were in use on Australia's Hamersley Iron before being sent to the U.S.
