Burlington Northern EMD E9 No. 9907 sits alongside two of its replacements—Metra EMD F40PHM-2 Nos. 189 and 191—at Hill Yard in Aurora, Illinois, on February 22, 1992. Metra bought 30 of these 3,200 hp locomotives units in 1991-92. No different mechanically than a EMD F40PH-2, but the streamlined cab and built-out windows give them a distinctive profile. For some, the unique slanted windows and lack of a front nose gave the locomotives the informal nickname ‘Winnebagos’ after the popular line of similar-looking recreational vehicles.
