https://www.facebook.com/groups/AmtraksEmpireBuilder/permalink/1676177812664078/Got word today that effective January 11, 2016, schedule of the eastbound Empire Builder will change to move some (but not enough) of the fat toward the east end of the run, rather than the west end, which does no good for an eastward train.
Trains 8 and 28 will still leave Seattle and Portland at the same time. Train 28 arrives in Spokane at the same time, but train 8 will arrive in Spokane 10 minutes earlier and depart 10 minutes earlier at 120 AM instead of 130 AM. (Why Amtrak thinks they still need 45 minutes dwell in Spokane is a mystery; their claim is they need it for "switching"). The train will operate 10 minutes earlier as far as Cut Bank, but then, instead of 58 minutes of running time for the 30 minute (including station dwell time) trip to Shelby, running time will be reduced to 43 minutes, which still allows for a a bit of padding at Whitefish and Shelby. Departure time from Shelby will be 25 minutes earlier, and the train will operate 25 minutes earlier to Stanley departing there at 746 PM. Times in Minot remain unchanged at 922 PM arrival and 942 PM departure. Times between Minot and St. Cloud inclusive remain unchanged, but times for St. Paul change a few minutes to 743 AM arrival and 800 AM departure (3 minutes earlier than at present). Times for stations Red Wing to Chicago are unchanged.
The main reason for the change to help BNSF to make incentive payments for the train, which is measured in segments, Seattle-Spokane, Portland-Spokane, Spokane-Shelby, Shelby-Minot, and Minot-St. Anthony (where the train enters Minnesota Commerical Railroad trackage). BNSF often made incentives west of Shelby where the all the fat in the schedule was, but east of Shelby, if delayed at all, the train would be late arriving at Minot and St. Paul and lose those segments, which amount to about $15,000 per train.
The source is reliable, AFAIK.
