The UP obliged with a stack train part way through the proceedings. This is pretty typical for this area, two reasonably new units with a but-load of stack cars. These containers are heading inland and will be loaded with all manner of cheap stuff from China and Taiwan. The train is travelling at about 60 mph. It’s pretty flat between here and Sacramento but he’ll slow down to about half his current speed for the curves on the shoreline of San Pablo Bay a few miles ahead.
