Is it that time of year again?

Is it that time of year again where BNSF runs some of the Coal Trains on the UP overland route?
I shot this on the Arlington hill last Sunday. Allan.

why would this be a BNSF coal train, instead of a leased engine on an UP train?[%-)]

I’d put my money on this train being a run through to a destination on UP. Or, a UP originated train going to a power plant served by BNSF. Or perhaps UP owed BNSF some “hours”.

No it was not a leased power Train.
