During the summer of 1977, the L&N had use of CN GP38-2's. These had the unique Canadian safety cab. I was staying at Pascagoula for the summer and drove the line from there to Mobile hoping for a train with one of these units. Good photo locations don't exist since the sun is directly overhead, and even though the road parallels the tracks there are not many open spots. I caught this westbound at St. Elmo, AL, with a CN unit as the last unit. I don't think the CN units ever ran in the lead.
