Sleet falling drones out the sound of EMD and GE's thundering up the 1.6% grade out of Coldstream Canyon. The wet rails are giving this SD9043MAC some troubles, and their speed is down to 11MPH, luckily, summit is only four miles away and then the next adventure of coming down the 2% grade in the snow begins... Oh, yeah, the engineer reported he had no dynamic brakes on the leader.
