Here’s a view as the cars flow off the north leg of the wye. You can see the grade quite distinctly here. Stege has an interesting track configuration including the wye which is elevated above I-580, a compact siding and the Waterside Drill track. About a mile toward Oakland, the double track UP main and the Waterside Drill are tied by four sets of crossovers enabling trains to transfer from any track to any other track in both directions.
These coal cars are headed to the Waterside Drill on the other side of the Stege crossovers is where the UP collects cars set out by the Richmond Pacific. The UP collects the cars using a Roseville bound train (M-OARV) which shows up daily in the evenings usually after 9:00pm.
