CP 6644 leads CP 651 WB in Elm Grove, WI on March 30th, 2021. This was a total surprise to me as this train usually goes to Mason City, Iowa, but INSTEAD, it went to Minnesota. And another thing that surprised me was that CP 6644 was leading. Since most SD70ACU's can't lead in the U.S due to some mechanical issues, CP 6644 is one of many SD70ACU's to lead in the U.S. This is a very nice treat to end the month of March!
