Rich, I interpret what you are saying as supportive of my "theory". This may well be established history to those that have the right reading material. Go to the area along San Bernardino Ave by the old Norton AFB, look for S. Mountain View Ave. In fact go to Bing maps and zoom in on that area and switch to Satellite view and you can see the old PE bridge across the Santa Ana (La Quinto). From S. Mountain View Ave., just follow the street line to the river and you will see the bridge. It appears that any visual trace of the ROW from the bridge up to 3rd has been obliterated by subsequent construction. There was some trackage along Mill St. at one time that went into the Orange Show grounds. I can vaguely remember a PE local working box reefers into the grounds. The main point I was trying to establish is that for a farewell fantrip in 1951 to have taken a PE passenger car down to the Sunkist-Crown Jewell area, there had to have been continuous 600 V. juice available from San Berdoo to there, and suggests that the two lines (SP,PE)to Redlands must have been separate until that time. I didn't think the part of the SP line that went south of I-10 (once US 99)survived after the "splicing" of the two lines. I also fondly remember the short 45 degree staff signals that had a permanent yellow signal light that graced the street running areas to warn of an impending interlocked crossing. I last saw one of those along Orange Ave in Riverside in 1974. It warned of an interlocker at the east end of the US 395 bridge covering the ATSF crossing(Riverside Jct). There were ones for the two interlocked crossings on Rialto Ave. as well as cantilevers holding the signals heads(semaphores and later searchlight). Even though the tracks were trimmed to just north of the ATSF Pasadena sub in Rialto before I was born, the two interlocking signals that covered the removed diamond that displayed to ATSF remained in place for years. I would love to find people and pictures from the area that may have been culled from the published books on the PE that show some of these details. I have always felt that the east end of the PE was sorely overlooked and undercovered. I have material that can't be transmitted by post that may help.
