Well, the plans have changed once again. The 5057 is evidently moving now!
We received a report last night that the 5057 has been put on a train at Riverbank, CA and moved to a siding at Duffy, 15 miles north of Riverbank. At last report, a crew was on the train but it had not departed yet. It is likely heading north now.
The weather should be decent today, so we hope people are able to get out and take photos and/or video of the 5057 as it heads north.
UPDATE: The 5057 sat at Oroville, CA all day because the Union Pacific was doing track work. It is on the move again this evening.
