The 4449 Daylight trips are not scheduled, so they will leave after Amtrak leaves PUS, and when the dispatcher gives them the signal. I'm not trying to be a smart - ass ( at the moment ), it's just the way BNSF handles 4449 trips. Once they're on the high iron the DS often gives them priority clear through to Wishram, though such a short train on the busy single - track Fallbridge Sub can and will spend some time in the hole. Once on the less - busy Oregon Trunk they usually have clear track all the way to Bend.
