Description:
Flying white extra flags and trailing a long line of iced and loaded refrigerator cars as she enters the yards at Cheyenne, Wyoming is Union Pacific MC-2 class "Mallet Consolidation" number 3610. The big coal-burning 2-8-8-0 "Mallet" articulated was built by the Schenectady plant of the American Locomotive Company, construction number 58272, in May of 1918. Nicknamed "Bull Mooses" by their crews, eventually the Union Pacific would roster seventy of these slow but powerful locomotives. They were succesful enough that between 1937 and 1943 all were simpled and upgraded. Number 3610 would emerge from the shops as a SA-C-2 class and carrying the new number 3510.
