Caption: I don't have the dates pinned down but I believe sometime in mid- to late 1985, CPR began operating what was described as "SOO business" via Montreal/Chicago routings and numbered the trains 500-501-502-503 ( at least). Anyway here's eastbound 502 at Center Street in Chatham as he cuts the city in half during his passage. SOO 6620 is leading CP SD-40's 5546 and 5528, which in turn are hauling dead, leased GATX power SD-40 5081 and 5073 still in Missouri Pacific paint. In 1987 CPR leased 10 of these units from GATX Leasing but this was the only time I caught them on film. They were enroute to Toronto or Montreal for placement in service. Trains 501 and 502 were usually daytime passings in the Chatham area, so I did shoot them a few times (between work and family etc). This elevator, whose name I've long since forgotten, is no longer in existence.
