Thanks for the comments! According to a couple of the "old heads' that are left from those days, there never was a wye at Aurora. You would have to back out on the main and continue south. Operations in 1947 are still a bit of a mystery since there is only one old guy I know who went down there once on a student trip. They took the tiny 2-6-2 #132 all the way from Stockton to Turlock and back which made for just under a 16 hour day. I do need to incorporate a wye in the Turlock section at the end of the intermediate level however, at the SP interchange.
In 1947 the railroad owned only 3 locomotives, electric motor 100, 44 tonner 135, and the 132, which was former Sierra Railway #32. I have yet to model the 132. I hope to get my scratchbuilding skills honed a bit before I attempt that one...
BTW I used AutoCad LT 2000 to draw up the plan. A bit labor intensive but it's what I have...
