MRL Special ACE's lead a manifest up Mullan Pass 3/5/23

Decided to go by the Helena depot on my way home this morning and found the MRL manifest M-LAUMIS (Laurel to Missoula) getting ready to depart. I figured I would watch it depart when I noticed that the 4404 (Essential workers unit) and 4407 (Veterans unit) were on the head end of this train. I rushed home and grabbed my filming gear after he departed the yard. I then headed to Tobin to watch the action and then chase it as far as I could up the pass. After heading back towards Helena, I caught the detector at Weed MP 15.9, reporting on a helper set descending the pass. I set back up at Tobin and watched the helper set as it returned to Helena.
