Northern Lines Railway is a little short line out of St. Cloud. While I was at the Granite City Train Show last year at the Armory, I noticed these GP7s parked in the yard out back. I was unaware of who these belonged until now. The paint schemes on 1411 and 1602 are definitely Burlington Northern and possibly the former owner of those engines. The 400 seems like a familiar paint maybe Indiana Harbor Belt or Bessemer Lake Erie. However I have found nothing exactly resembling it. This is all the power which the short line uses over its 25 miles of trackage between St. Cloud and Collegeville to the west and Rockville to the south.
There are a few videos out there of the 1511 and 400 in action.
