Photo #1 is of Train 12 on the main track at the north end (timetable west) of the Newark yard. The Santa Clara Siding is visible on the other side of the mainline. The track taking off to the right is the "Rickwell" (sp?) which was one of two leads going from the mainline into that end of the yard. The south leg of the wye heading to Centerville and Niles is barely visible in the distance beyond that. The switches and signals for all of these tracks were controlled by the operator at Newark Tower, which was actually just a small single-story building located west of the east wye switch. The Eucalyptus trees in the far distance on the other side of the train marked the west end of the Santa Clara Sliding "Extension" and was where units for the various Newark locals were often parked. The Dumbarton wye and the Newark depot (the area is now called Carter by UP) are out of sight and around a curve beyond that. Directly behind where you are standing is a grade crossing (might be Central Avenue, but it's been at least 25 years since I've been there, so my memory is fuzzy - look it up on a map if you wish), and behind the crossing is the Newark yard.
