An unique operation on Montana Rail Link’s 9.5-mile Harrison branch is that the local has to go through four cattle gates twice on each round trip. The train has to stop, with the crew unlocking and opening the gate, letting the train through, and then closing the gate after each passage. Here, Engineer Charlie Kehrwald (both MRL locomotive crews are engineers) opens a gate about two miles north of Harrison as GP35 No. 403 stands by. Branch line railroading at its best!
