All-Time Soo Line RR Locomotive Roster
Part Two-Diesel Locomotives

Here I am attempting to document all the diesel locomotives owned by the Soo Line Railroad Company, 1960-1992.  I am not documenting dispositions at this time; there have been so many since 1992 that I find it impossible to keep track of them.  Numbers in (parentheses) indicate an assigned series in which not all locomotives were renumbered.
