Union Pacific's UEOEY9-10 ethanol train rolls through Emeryville led by SD70Ms #3784 and #4321 with Norfolk Southern C40-8W #8457 sandwiched in between. NS 8457 is an ex-Conrail unit.
Photos I've taken of trains with locomotives of railroads considered foreign in California (NS, CSX, CN, CP, etc) and "Special Interest" locomotives on them.
