CN 6765 Alco FPA-4 Diesel Locomotive, served CN and VIA in passenger service in the Maritimes and Quebec 1960's - 1980's. I got to ride this baby a few times as youngster at the Fairview Roundhouse (Halifax) while visiting my Dad.
ALCO RS-1 The ALCO RS-1 was a 4-axle diesel-electric locomotive built by Alco-GE between 1941 and 1953 and the American Locomotive Company from 1953 to 1960. This model has the distinction of having the longest production run of any diesel locomotive for the North American market. The carbody configuration of the RS-1 pioneered the road switcher type of diesel locomotive. Most locomotives built since have followed this basic design.
