Diesel Locomotives, 1991-2000

Still short of motive power following the Milwaukee Road merger, Soo Line turned to the rebuild market in the early 1990s for additional motive power. The result was some unusual locomotives, unique to the Soo Line. Rebuilt from old GP9s and GP30s by Generation II Locomotive of Babbitt, MN, they featured Caterpillar prime movers and many other new components. Here GP15C 4102 and a Milwaukee Road MP15AC head past Milepost 409 at Dayton's Bluff in St. Paul, MN on January 8, 1995.
