Nice pictures! That unit was here in Houston some time last year. I only caught a distant glimpse of it at Settegast Yard, and have yet to see it again.
I caught this unit at Fife Yard in 2007, as part of the 844/4449 doubleheader. It's the only UP heritage unit I have seen.
I must say that I am impressed with the apparent cleanliness of the unit, the close up showing the louvres indicates the locomotive is being exceptionally well cared for. Ted (Teditor) Freeman
Is there a place to look up where that locomotive will be at certain times? I wish I had known it was debuted right here in my backyard...
