Great details. The first Y rail and the branch rail are definitely from Plarail designs. It seems that your set was manufactured during the 1960-1964 TOMIYAMA times. The 3rd last image definitely resembles all the parts from the old TOMY sets, like the standing signals, sloped end and the junction. The buffers did not appear in TOMY sets so it is original.
The black rails, child guidance rails and TOMY rails have a great resemblance. Are they partners at one time or they just didn't copyright their rails?
