I have been showcasing about 1 railroad related image per post it seems... so here is my one image for this post. This is a profile image of the signals which protect eastward and westward movement of the Union Pacific Railroad & BNSF Railway as they enter and exit the Alameda Corridor which takes trains from Los Angeles to points in Wilmington or Long Beach, CA
The next two images are sort of railroad related. They are both the west and east sides of Pabco Paper which resides in Vernon, CA. Vernon is a mostly industrial zoned city and this paper mill rest on the southern edge of the city alongside BNSF's Malabar Yard.
