One of the first order of only three GP7's. GP7 1500 hp 65mph GMD A324 3/52 8410 and 8411 were equipped with steam generators for passenger service. (removed 1955) Typically, at this early date only small orders of diesels were acquired by the CPR as they tested performance and suitable usage. These three units were for Calgary-Revelstoke way freight service as well as winter ski trains. This was followed the next year by an order for 14 units, after which came large orders totalling 200, of the new, more powerful GP9 which has proven to be an exceptional and long-lasting locomotive. In fact, most were remanufactured by the CPR into modernized yard engines which are still at work 50 years later. 8411 was rebuilt at Ogden being outshopped 6/82 as 1506 and currently (2006) assigned to Winnipeg.
