During the years that 1685 ventured beyond Winnipeg, it regularly traveled to Emerson on the daily freight until that was discontinued. At times it assisted with the former Great Northern passenger train which ran between Minneapolis and Winnipeg. As built, 1685 originally had a steam generator for that purpose. 1685 was not substantially modified over the years. Other than carrying the Burlington Northern paint scheme when BN took over the Midland, and then again when she became BNSF 1685 in 1999, the only major modification was the removal of the steam generator. According to motive power rosters, 1685 was the last GP-9 owned by BNSF.
