Montana Rail Link SD40-2XR No. 259 powers a “Jimbo” work train that has cleared for a westbound freight in Skyline siding on the east slope of Mullan Pass in Montana on June 29, 2016. No. 259 is former Burlington Northern SD40 No. 6324 that MRL has rebuilt to “extra reliable” Dash 2 standards in its own Livingston Shops.
