Montana Rail Link's M-LAUMIS1-18 (Laurel-Missoula) manifest freight blasts out of the tunnel at the top of Bozeman Pass at West End, Montana. MRL SD70ACe's 4401 and 4400 (and a tag-along GP35) lead the train. The pair is MRL's newest motive power, and was delivered to the railroad just 16 days earlier.
