Allan,
Do you have any idea when the Standard Gauge line was built? Did it ever have any interaction with two foot gauge track in the same yard either before or after the SR&RL was scrapped? From what I've heard there were local pockets of two foot gauge operating in Franklin County long after 1936, mostly in lumber yards. That's where SR&RL bus #5 spent her finals days.
From what I've been able to dig up about it the line was about half a mile long and ran between two mill complexes. The reason that it was Wide Gauge and not "Franklin County Standard Gauge" is the cars were about 16 feet wide to allow lumber to be loaded crosswise.
As standard gauge lines go, it was not exactly the Union Pacific, but it was 4' 8.5" right in the heart of Sandy River country.
-strange but true!
