Electro-Motive model GP40 road switcher stands in front of a steam-era roundhouse at La Crosse, Wisconsin. This GP40 was built for BN constituent railroad Chicago, Burlington & Quincy in 1966. CB&Q was merged with Great Northern, Northern Pacific, and Spokane, Portland & Seattle in 1970 to form the Burlington Northern. The GP40 was among General Motors Electro-Motive Division standard 645-series diesel locomotives introduced in 1965-1966. It was powered by a 16-645E3 diesel rated at 3,000 hp. The view from the front shows the cab style common to many Electro-Motive diesels of the period, including both four and six-axle types. The roundhouse was razed in October 1982.
