caption_attribution_description: Canadian National operated over BNSF between Duluth and Chicago through the use of a &quot;Haulage Agreement.&quot; They were CN's trains and locomotives but they were operated by BNSF train crews. Unlike trackage rights, a haulage agreement did not require regulatory approval to implement.
context_page_description: The EMD SD75I is a road switcher diesel-electric locomotive produced by General Motors Electro-Motive Division between 1996 and 1999.
  This unit is the same as the EMD SD75M, with 4,300 horsepower, HTCR radial trucks and a 72-foot-4-inch frame. The only difference between the two models is the cab. The "I" in the model designation stands for "Isolated Cab". This type of cab is recognized by a seam separating the nose and cab components. This seam is the rubber that dampens vibration and cuts down on noise, because the cab is not attached directly to the frame on the unit. This was the last model that used the "I" designation in the model name; all further units had the isolated cab, but the model designation continued to use the "M". Buyers included Canadian National, the largest buyer with 175 units, Burlington Northern Santa Fe with 26, and Ontario Northland Railway with 6.
