Union Pacific, BNSF, and Amtrak California San Joaquin trains in the Central Valley. This visit to the valley was finally more of a "quantity over quality" day unlike the past couple of trips. BNSF provided the most action as usual (including a couple foreign visitors) with the highlights being a Norfolk Southern AC44C6M, a Ferromex SD70ACe, and a BNSF Warbonnet C44-9W!
