A single example of the very similar model RSD-17 was built by the Montreal Locomotive Works in 1957. After demonstrating on the Canadian Pacific (as #7007), the Canadian National (as #3899), and the Pacific Great Eastern (as #624), the locomotive was purchased by the Canadian Pacific (as #8921). Nicknamed "The Empress of Agincourt" (for its common presence around Toronto's Agincourt yard), the locomotive served the railroad until 1995, when truck problems forced its retirement.
