Diesel Locomotives, 1986-1990
Following the Milwaukee Road merger, Soo units began to venture
off-property more often in run-through service and transfer operations.
Hence, it also became more likely that one would find foreign-road locomotives
on the Soo repaying horsepower hours. That may or may not be the case here,
as we see Soo Line SD40-2 763 and three units from Burlington Northern at
Dayton's Bluff in St. Paul, MN on February 4, 1990.
