Caption: Drumming in the distance suggested that CLC-FM's were on CN Train 55, the Lakeshore. Sure enough, not one but two CLC passenger units were in charge of the Montreal - Toronto train on the evening of Monday, August 21, 1967, just east of the station at Marysville, Ontario. Marysville is at Mileage 207 of the Kingston Sub while the train is passing under Kings Highway 2. The trailing units were CPB16-5 6804 and MLW FPA-2u 6759. Train 55, the Bonaventure, was due at Belleville, Mileage 220.7, at 7.15 p.m., having left Montreal at 3.35 p.m. and, the previous stop, Kingston at 6.28 p.m. It was due in Toronto at 9.20 p.m. The Bonaventure was one of five daily Montreal - Toronto trains in the busy Centennial Year that attracted world-wide visitors to the Expo 67 World's Fair site in Montreal.

CPA-16-5 6703 was part of six A-B sets purchased by the CNR from the Canadian Locomotive Company in nearby Kingston. A pair of CPA24-5s, 4801 and 4802, toured the CNR beginning in August 1950 as Fairbanks Morse started its effective control of CLC. (After the tour, FM sold the demonstrators as New Haven 790 and 791.) Although GMD and MLW also provided demonstrators around this time, no order was forthcoming from the CNR for passenger units until 1954. CLC was modestly successful in selling units to both Canadian National and Canadian Pacific. Amongst other models, the CNR took sixty 1200hp roadswitchers between 1951 and 1956 while the CPR bought fifty H16-44s. CLC delivered the 6703 in early 1955, and it became the last active CLC cab unit on CN when it was retired in May 1969.
