Diesel Locomotives, 1940-1969

After the December 30, 1960 merger of the old Soo Line, the old Wisconsin Central, and the Duluth, South Shore and Atlantic, the "new" Soo Line inherited the locomotives of all predecessor roads. While Soo and WC engines all wore the same paint scheme, the DSS&A units carried a distinctly different scheme of red, yellow, and green. In the 1960s, Soo Line, to save money, simply relettered many of the DSS&A units "SOO LINE", retaining their bright colors. Soo Line AS616 390, a Baldwin product, is seen here at Marquette, MI in 1967, working the rails it no doubt worked frequently as a DSS&A unit.
