These are the first two Montana Rail Link SD70ACes I've ever seen! They are paired with an SDP40R (formerly BN) and the Laurel Yard Utility Crew is building the "LM". That is short for the "Laurel to Missoula", an MRL manifest that runs between the yards in Laurel and Missoula. Its counterpart is the "ML", and both trains are run as needed by either yard.
