The South Bay area of Los Angeles does not have a lot of railroading, but what it does have (the UP El Segundo, the UP Torrance, and the BNSF Harbor Sub stub) is fairly consistently scheduled. (Note, there's also the contracted switching company at the Chevron plant, but catching them in daylight is a blue moon event that I have never accomplished.)
For the last few years, Union Pacific has been transitioning to Gensets on their runs on the few remaining old PE lines. Now BNSF has decided they will make it homogeneous by bringing their own pair of Gensets in to work the 711 job from Watson to El Segundo.
 
This is the face of South Bay railroading today - first up is the BNSF job climbing Monaco Hill on its way from Chevron to Alcoa.
 
 
Second image is of the UP's LOW10 passing one of two remaining wig-wag signals on the Crenshaw Lumber spur in Gardena. This used to be the Redondo Beach via Gardena Line of the PE.
 
 
And just to cap it off, a shot I may have shared earlier, of a Pacific Harbor Line Genset at the Wilmington Jct, backing onto a stub of what was once the PE's San Pedro via Torrance line.
 
 
Thanks for looking, and corrections are welcome.
